Google will show how much memory Chrome tabs use
The Google Chrome browser has a new way to check the amount of memory used by each open tab, 9to5google reports.
The new feature is available for users of Mac, Windows, ChromeOS, and other operating systems.
Now, when a user hovers over a page in the tab bar, in addition to the page name and domain, they can also see Memory Usage.
This feature allows you to see which pages are particularly loaded on the system.
To check the memory usage, hover over the tab and make sure your browser is updated to the latest version.
