The latest update to the Firefox browser can show how much memory individual tabs and add-ons are using up.
How it works?
You can find the memory information either by: clicking on the menu button and then navigating to More > Task Manager or by typing “about: performance” (without quotation marks) in the address bar. The current energy consumption of tabs and add-ons is also displayed.
Meanwhile, the Privacy & Security menu has been made clearer and it should now be easier to set up page content blockers.
And, there you go.
