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?
Every tab that you leave open in your web browser consumes some percentage of your system’s resources. To deal with this problem, some web browsers have a built-in tab sleeping feature. If you are a Google Chrome or Microsoft Edge user, you might have noticed that when you switch to another tab after spending some time on a particular tab, Chrome or Edge reloads that tab. This is the tab sleeping feature of Chrome and Edge. The tab sleeping feature suspends the tabs that remain inactive for a particular time. When a user returns to the inactive tabs, the web browser loads those tabs again. By doing this, Chrome and Edge manage the memory of the user’s 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!

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.
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.
