The latest version of the Firefox browser shows you how much memory individual tabs and add-ons are using up.
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.
In addition, the Privacy & Security menu has been made clearer and it should now be easier to set up page content blockers.
Firefox 65 also supports WebP images which are around one-third smaller than the usual JPEG or PNG formats used on webpages but without visible quality differences. WebP also allows transparency and animation such as GIFs, and is already supported by browsers like Chrome and Opera. – dpa
