Suggested April 2024 Is It Bad To Keep Multiple Tabs Open On Your Computer?

Is it bad to have many tabs open in your browser? While working on the internet, we usually keep opening websites in separate tabs without closing the previously opened tabs in our web browser. Every program or software that we open on our computer uses some of our system resources, including the memory (RAM) and the CPU. Similarly, a web browser also consumes some percentage of our system’s RAM and CPU. The RAM and CPU usage by a web browser increases as we start opening multiple tabs.

You might have noticed that after opening a certain amount of tabs in a web browser, the performance of your system decreases slightly, and the web browser becomes slow. The number of tabs a user can open in a browser actually depends on his system’s hardware. That’s why it varies from user to user.

What happens if you open too many tabs?

Opening too many tabs puts a strain on your computer’s CPU. Every tab that you open in your web browser consumes some amount of your system’s memory. Hence, the more tabs you open in a web browser, the more RAM your browser will consume. That’s why opening too many tabs will result in performance issues and may cause your system to freeze or crash.

Is it bad to keep multiple tabs open on your computer?

As explained above, opening multiple tabs in a web browser impacts the browser’s and system’s performance. You can view how much percentage of your system’s RAM and CPU a web browser is using by opening the Task Manager. The number of tabs that you can leave open on your computer depends on different factors.

Your computer’s hardware: Undoubtedly, a computer with 4 GB of RAM has a lower performance as compared to a computer with more RAM, say 8 GB or 16 GB. However, there are other factors too responsible for a system’s performance. The computers with more RAM can provide better resources to web browsers as compared to computers with less RAM. If your computer has less RAM, say 4 GB, you will experience performance issues after opening multiple tabs.

The graphics of a web page: Some websites have heavy graphics. Due to this, such websites require more resources from a system. Opening such websites will put more strain on your system due to which you will experience performance issues with your system. Google Maps and Google Earth are some of the websites that use heavy graphics.

Does having multiple tabs open slow down computer?

Hence, if your web browser has a sleeping tab feature, leaving multiple tabs open will not impact the performance of your system. On the other hand, if your web browser does not have the sleeping tabs feature, you can open only a limited number of tabs after which you will start facing performance issues with your system. In order to manage this problem, you have to close some of the opened tabs.

The number of browser addons & extensions you have installed also takes it toll!

Use built-in Task Manager to manage tabs in a web browser

Popular web browsers, like Firefox, Chrome, and Edge come with a built-in Task Manager that lets users know which tabs are consuming high resources of their system. While working with multiple tabs in a web browser, you can use the built-in Task Manager to close those tabs that are consuming high Ram and putting more load on your CPU.

Here, we will show you how to use the built-in Task Manager to manage tabs in:

Firefox

Chrome

Edge

1] How to use built-in Task Manager in Firefox to manage tabs

Follow the steps written below to open the built-in Task Manager in Firefox:

Open Firefox.

Press Ctrl + T to open a new tab.

Type about:performance in the address bar of Firefox.

This will open the Task Manager in Firefox where you can see which tabs are taking the highest resources from your system. Now, you can close those tabs to manage your system’s RAM.

2] How to use built-in Task Manager in Chrome to manage tabs

The following steps will help you open the Task Manager in Chrome:

Open Google Chrome.

3] How to use built-in Task Manager in Edge to manage tabs

Follow the below steps to open the Task Manager in Edge:

Open Microsoft Edge.

When the Task Manager appears, you can view which tabs are using most of your RAM. To close a particular tab, select that tab in the Task Manager and select End Process.

This is how you can manage tabs in different web browsers so that opening multiple tabs will not impact your system’s performance.

Does having multiple tabs open slow down the computer?

Leaving multiple tabs open in a web browser slows down your computer. This is because every tab uses some percentage of your system’s RAM. Therefore, if you open multiple tabs in your web browser, the maximum part of your computer’s RAM will be used by your web browser, as a result of which your system will have less free RAM to manage other tasks.

Does having multiple tabs open drain battery?

Generally speaking, it is logical to expect that the more tabs you have open, the more the resource consumption and consequently power consumption. But the actual battery drain is negligible and studies have also shown that the more tabs you have open, the less the effect each new tab has on the battery life.

Closing Words

How many tabs we can open in our web browser actually depends on the hardware of our system. If you have a high-end PC, this number is comparatively larger than those who have a PC with less RAM. However, every machine has a limit. After a certain point, you will start experiencing performance issues with your system. Therefore, it is better to close the tabs that are not in use.

We’d love to know how many browser tabs you have open at any point in time, normally!

To open a certain .tbl file on your computer you have to use suitable software.

A .tbl file is the shortened version of the word table and is a type of file often used as a generic table file.

If you have wondered how to open a .tbl file, Adobe’s tool can be used for the task.

TBL files can also be opened and processed with an app from the Office suite.

Get the right software to support your ideas!

Creative Cloud is all you need to bring your imagination to life. Use all the Adobe apps and combine them for amazing results. Using Creative Cloud you can make, edit, and render in different formats:

Photos

Videos

Songs

3D models & infographics

Many other artworks

Get all apps at a special price!

Almost surprisingly, the .tbl file extension is fairly common. A large variety of programs use it. Despite its general ubiquity, you may still be curious about what information a TBL file contains.

As you might have guessed, TBL is a shortened version of the word table, and thus what we can say that it contains tabular data for programs to use.

This may confuse you a bit. Why would a program use a .tbl file instead of a database or database file?

TBL files can be more flexible and easier to work with than databases, especially if you’re working with a small set of data. They’re particularly great for handling and archiving directory list data.

While software like Adobe InDesign, Creo, FX AccuCharts, Chem3D Ultra, and AutoCAD Civil 3D can be used to create and access .tbl files, you can create and modify your own using Microsoft Excel.

Once the file is saved to your computer you can then convert it into a .tbl file by changing the extension. In gaming, .tbl files are used for creating mods.

Computer games usually save information in the form of XML and TBL files. These can be accessed and changed using a text editor or Excel.

How do I open a .tbl file on my computer? 1. Use Microsoft Excel 2. Use third-party programs

Use Adobe InDesign

Adobe InDesign is a professional layout program for print and digital content. Many of you have heard of it before as the ideal tool to create multicolumn pages with rich graphics, images, and tables.

Expert tip:

The authority of Adobe InDesign is being constantly challenged and it’s pretty much up for every single task, as difficult as it may seem.

If you are new to this program, then let us tell you that opening documents and template files requires minimum effort, .tbl files included.

This also applies to InDesign Markup (.idml) files, InDesign Interchange (.inx) files, and even QuarkXPress Passport 4.1 files.

⇒ Get Adobe InDesign

Use Autodesk Civil 3D

You may have noticed that a long list of CAD (computer-aided design) programs use .tbl files. An especially popular one is Autodesk Civil 3D.

If you can’t use Autodesk to open the file, then a good alternative is Microsoft Excel. If neither Autodesk Civil 3D nor Excel can open the file, then you can try using a text editor to open the text.

Be careful not to modify or change anything in your file, as this may stop some programs from working.

How To Keep Your Computer Secure While Traveling

Traveling with connected devices could open you up to data breaches or cyberattacks.

It’s important to take protective steps before traveling with your devices.

Failure to take the proper cybersecurity measures when traveling could put your entire business at risk.

This article is for business owners and professionals who plan to travel with connected devices like laptops, smartphones or tablets.

In the office or at home, you may be protected from online threats thanks to a robust cybersecurity solution for your internal network. But what about when you’re on a trip? You won’t be protected by your office’s network security, and must depend on hotel and conference center Wi-Fi, which aren’t always safe. Using your mobile devices on the go increases your risk of being exposed to online threats – hackers are always looking for opportunities to infect mobile devices and use them to gain access to the greater network.

When on a business trip and constantly using your mobile device for work, you need to be wary that you’re more at risk of attack. There are certain best practices that all employees should follow when traveling with your work devices.

Editor’s note: Looking for the right mobile device management solution for your business? Fill out the below questionnaire to have our vendor partners contact you about your needs.

How to configure your devices for travel

These are some cybersecurity musts when traveling with your connected devices.

1. Password-lock your devices.

Always make sure your devices are locked and password-protected. Should your device be lost or stolen, your first line of defense is a strong password. Even simple storage devices like your USB thumb drive should have a password.

2. Enable 2FA or MFA.

If possible, enable two-factor or multifactor authentication on your devices. On top of a password, use a credential system that requires you to insert an unlocking USB device or a biometric lock, assuming that’s a feature on the device.

3. Encrypt your data.

If you’re traveling with sensitive data on your laptop, it’s best to fully encrypt your device with disk encryption software. This locks your data behind more authentication factors and encrypts it, so if it falls into the wrong hands, they can’t strong-arm their way through to the disk. The data is scrambled and impossible to decipher without the password.

Ideally, you shouldn’t store sensitive data on your device. Instead, access it through the cloud over an encrypted connection such as a cloud access security broker (CASB).

“Don’t store sensitive work data on a mobile device, period,” said Mendy Newman, vice president of cybersecurity product management for Ericom Software. “Mobile devices can easily fall into the wrong hands, where they are subject to tampering by sophisticated cybercriminals who are only too happy to sell that data to the highest bidder. Instead, data should remain securely within the corporate data center and accessed remotely over an encrypted connection that protects the session from prying eyes, even when using public Wi-Fi.”

4. Turn off Wi-Fi and Bluetooth auto-connect.

A feature on many laptops and mobile phones is an auto-connect option for Wi-Fi and Bluetooth connections. Make sure this is off, as you don’t want to auto-connect to just any Wi-Fi connection you pass. Most public Wi-Fi connections are unsecured, and some can be set up for malicious purposes to gain access or download malware to your device.

Tip

Before traveling, back up your sensitive or critical information on an external device or to the cloud, and make sure you have the latest version of all of your software applications.

Fix Microsoft Edge Keeps Opening Multiple Tabs

Does Microsoft Edge keep opening multiple tabs on startup? If yes, the solutions provided in this post will help you fix the problem. According to some users, Edge is opening some random web pages in multiple tabs on startup, whereas, some have reported that Edge is opening hundreds of tabs on the Microsoft Help page. Users have also scanned their systems with antivirus and antimalware software but the software did not show any threat.

You can also use Microsoft Safety Scanner or some Standalone On-demand Antivirus Scanner.

4] Repair or Reset Microsoft Edge

One effective solution to fix the problem that you are currently experiencing is to reset Edge settings to default. If your system is running on Windows 10, you will find the option to reset Edge in the Windows 10 Settings app.

In Windows 11 Settings, the option to reset Edge is not available. Hence, you can reset Microsoft Edge settings to default directly from the Edge browser.

The above process will restore the default settings. Hence, after resetting Edge, it should not open multiple tabs on its own on startup.

5] Download and reinstall Edge

If nothing helps, you can download Edge browser setup from chúng tôi and fresh-install it.

How do I stop Edge from opening multiple tabs?

If Edge is opening multiple tabs on its own on startup, you should check its settings. Microsoft Edge has an option that lets users make Edge open their favorite websites on startup. Another cause of this problem is virus or malware infection, Therefore, you should run an antivirus and antimalware scan.

If the problem persists, re-register Microsoft Edge or reset its settings to default to fix the problem.

Related: Chrome keep opening new tabs or windows on its own

Why does my browser keep opening new tabs?

If your browser, like Firefox, Chrome, etc., keeps opening new tabs by itself, you should run an antimalware scan. If your antimalware software does not find any threat in your system, there might be a problematic extension causing the problem. To check this, disable all the extensions one by one and then check if the problem disappears. This is a time-consuming process if you have a lot of extensions but it will help you solve your problem.

Hope this helps.

How To Fix “Your Computer Is Low On Memory” Error On Windows 10

Memory Is Not Disk Space

In this case “Memory” does not refer to hard drive space. It refers to RAM (Random Access Memory). That’s the fast working memory of your computer and exists as physical microchips, separate from the hard drives that permanently store your operating system, apps and data.

Table of Contents

This means that to fix this issue, you need to free up your computer’s working memory. However, it’s also doesn’t hurt to free up some disk space too if you’re running low.

Close Unneeded Programs (or Browser Tabs)

The most obvious thing to do is close programs that you don’t need. You can do this the usual way by simply using the X button at the top-right of the Window. If the program isn’t responding, you can end it the brute force way.

Open the Task Manager by using any of the following methods:

Remember to save your work before you close anything important.

If your web browser (we’re looking at you Chrome!) is the big memory hog, try closing some tabs instead of the whole program. Also read our article on how to get Chrome to use less memory.

After you’ve closed the offending app, start it up again. It may use less memory after it restarts.

Sometimes memory management goes awry in a way that can’t be fixed by closing apps. In this case, simply restarting your computer may do the trick.

Check That Your Paging File Is Okay

When you get the low memory warning, it means that this safety net has also filled up completely. If the above measures don’t work, it’s worth adjusting your paging file.

Another option is Disk Cleanup. Windows includes a handy Disk Cleanup utility that can quickly take care of a full hard drive. If your paging file is being squeezed through a lack of disk space, it’s worth trying this:

Under the General tab, select Disk Cleanup.

Check all the types of files that you want automatically removed.

Select Clean up system files.

After the cleanup is complete, you can close the disk properties window.

Check for Malware

There’s a small chance that malware (viruses or spyware) is responsible for the “Your Computer Is Low on Memory” warning message. 

To check for and remove malware, you need special software. Windows 10 has a built-in application known as Windows Defender. That’s good enough for most people, but if you’d like check out How to Scan for Malware in Windows 10 and How To Remove Stubborn Malware.

Check Your Minimum Requirements and Buy More RAM (Maybe)

If you’re getting low memory warnings with a specific application, make sure your system meets the minimum Windows 10 RAM requirements of the software you’re trying to run.

Allocate More RAM to Specific Apps

Sometimes you may not be running out of total RAM, but some applications may not be getting the RAM they need. Windows usually does a good job of prioritizing RAM, but you can manually override it if needed. Check out How to Allocate More RAM to Specific Apps in Windows to see how it’s done, along with related caveats.

Adjust Application Settings or Workload

Many programs can be tweaked to use less RAM. For example, Adobe Premiere Pro lets you adjust the maximum usable memory limit. This will free up memory for other apps.

Alternatively, you can reduce the amount of RAM an application needs by reducing the size of the data that it works with. For example, you might want to reduce the resolution of a picture or video that you’re trying to edit.

Keep It Stable, Stupid! How To Stress

Modern-day PCs are more reliable than ever before, but that doesn’t mean they’re infallible. Equipment failures still happen, however rarely, and even the beefiest of computer components aren’t worth their weight in silicon if they aren’t dependable. Thankfully, the hot and heavy world of stress testing can help to identify critical faults before your PC craps out in the middle of a critical operation.

Let’s make this processor squirm, shall we?

Why stress-test? Simple: To ensure the reliability and stability of your system. Even if a computer boots up and performs well under normal usage, fickle hardware can cause woes when you step up to heftier tasks, such as gaming or video editing. Stress-testing software places your components under an intense workload to simulate a worse-case scenario; if a component crashes, hangs, or otherwise fails a dedicated stress test, there’s a good chance that it won’t be reliable under a heavy everyday load. It’s best to uncover unstable components sooner rather than later, while they’re still under warranty.

Running stress tests can also let you know if you need additional cooling in your computer. If a graphics card or overclocked CPU consistently overheats and shuts down during a stress test, it’s time to dump the stock cooler, add a few case fans, and possibly even consider liquid cooling.

All that said, the actual process of stress testing isn’t terribly complicated, though it can be time-consuming. Ladies and gentlemen, it’s time to start your engines.

Laying the groundwork

Here’s a look at HWMonitor and SpeedFan’s interfaces side-by-side.

Actually, it isn’t. Before you start torturing your PC, you’re going to need a way to keep tabs on its screaming. CPUID’s HWMonitor software does exactly that, providing you with a real-time glimpse of your components’ temperatures, voltage, and fan speeds. SpeedFan does the same, though its interface isn’t quite as polished as HWMonitor’s.

You’ll want to have at least one of the two programs open during stress tests. While many components will automatically shut down if they overheat, not all will, and you want to pull the plug on your testing if your hardware hits dangerous heat levels. You can fry your components if a worst-case scenario occurs and you’re not paying attention. If you see CPU temperatures starting to creep north of 70 degrees Celsius, or graphics card temperatures around 105°C (though that varies by model—do your homework!), stop the test and add more cooling to your computer. You’ll also want to halt your testing if temperatures continuously hover around those marks for an extended period of time.

Push your CPU with Prime95

If you stress-test only a single component, stress-test your CPU. It’s that important—and it’s frequently the culprit behind an unstable system.

Prime95 includes three different “torture” tests.

IntelBurnTest is a nonofficial, user-friendly version of Intel’s brutal Linpack benchmark.

Want a second opinion? Different programs test CPUs in different ways. Hard-core types also hold IntelBurnTest and OCCT—two other CPU-stressing programs—in high regard. Both hit your processor hard and ramp temperatures up very rapidly, however, so keep a close eye on your system-monitoring software when you first start them up.

No matter which testing program you choose, run it for at least four hours; a full overnight run is preferable. Personally, I like to stress-test new PCs using Prime95’s Blend and Small FFT tests for at least twelve hours apiece, and I sometimes follow it up with an hour-long, High or Very High stress level IntelBurnTest run. Overkill? Maybe. But if your CPU survives all that, it’s definitely a keeper.

Ramp up your RAM

When it comes to seriously testing RAM, only one option is worth considering: MemTest86+. This tried-and-true diagnostic software has been around seemingly forever, and while it definitely looks its age—MemTest86+ rocks an ugly BIOS-esque interface—the program is just as effective now as it always has been.

Verifying your video card’s stability

Nope, that’s not the eye of Sauron, it’s the FurMark stress test.

Benchmarking tools abound, but FurMark was designed specifically to give your GPU a stress-inducing workout and punishes graphics cards much harder than the average game. This bad boy uses real-time renderings of furry objects undulating in front of groovy backgrounds to push your graphics card to its limits, complete with antialiasing and resolution options. Stick to the standard burn-in test, but keep an eye on HWMonitor and/or SpeedFan—FurMark gets your GPU very hot, very quickly. You won’t need to run FurMark for long. If your graphics card is going to crash or start tossing out funky visual artifacts, it will do so within 15 to 30 minutes.

Unigine’s “Valley” takes a more serene, Skyrim-inspired approach to stress testing.

Alternatively, Uningine—the makers of the popular Heaven graphics benchmark—recently released “Valley,” a new GPU stress-testing tool that’s a lot prettier and more peaceful-looking than Furmark. I haven’t had a chance to use it extensively, however.

What about the rest?

The CPU, GPU, and RAM are the only major system components you really need to worry about stress-testing. Should you benchmark your storage drives to make sure they’re delivering the promised data transfer rates? Sure—but that’s a performance issue, not a stability or reliability issue. I recommend checking a new hard disk drive’s health using a S.M.A.R.T. monitoring tool, but that’s about it, the usual “Make sure your data is backed up!” axiom aside.

Likewise, you can loop a long video with your display brightness on high if you’re worried about the battery life of your laptop, but again, it’s far from necessary and more of a benchmark test than a stress test.

While this guide can help ensure the stability of your system, the methods and tools outlined here are far from your only option. In fact, a plethora of different stress-testing strategies and software solutions exist out there in the wild. How do you stress test your PCs?
