Firefox & Chrome high CPU usage; Find the tab

Firefox or Chrome: Browsers have improved dramatically over the last decade. They are much faster and much easier to use. But although browsers seem to be perfect, they often experience problems such as memory leaks and high CPU usage.

Surely you've met it:

If you leave a multi-tabbed browser open for a long time, it will slowly start using more and more memory, but it also makes excessive use of your computer's CPU. Your only solution, of course, is to close the application, or close the tab that creates the biggest problem.Firefox

In modern browsers, you can simply close the high CPU tab.
Below we will see how you can find this tab.


Chrome has its own process manager. In Windows, if you open the process manager, you'll probably see too many Chrome exe running at the same time. It is an exe for each tab. In the unlikely event that Windows does not correctly report memory or CPU usage or do not see all of your tabs, you can use Chrome Process Manager.

Open a Chrome window and press the Shift + Esc keys together to open the process manager. You'll see a list of all the tabs you've opened and all of the extensions you've installed in your browser. You can sort the processes (short) with high to low usage. Select the high-CPU tab and click Process End to close it.


Firefox does not have a Task Manager like Chrome, but it has a built-in tool that shows performance statistics for tabs and add-ons. Open Firefox and enter the following text in the address bar.

about: performance

This page will give you a list of all your open tabs and add-ons installed in your browser. To view performance statistics for an add-on or tab, click the "More" button next to the tab or add-on.

You will see CPU usage and you can close or refresh the tab directly from this page. You can not sort the tabs in use, so you should look for the high-CPU tab.

Windows Task Manager

Of course, you can always use the Windows Task Manager to find a memory card or CPU.

Make sure that you group the processes by type and then sort the column by using the CPU.

By Firefox, the task manager will only report the use of the CPU for the current tab. You should separate the tabs into windows while observing the task manager.

By Chrome, the Windows Task Manager will show you the memory and CPU usage on individual tabs, but it will not display the titles of the tabs. So you can close some tabs you need. The Best Technology Site in Greecefgns
