Not grey enough.

Cool !

Right that needed

After firefox updated to v89, it messed up everything as usual and visually it would look either too dark or too white depending on the preinstalled theme chosen. The "Grey and Grey" theme saved my life. Nice grey shade and surprisingly sharp and easy to read font appearance. First time I come to rate a theme, and probably last, since I guess I am keeping it forever! Many thanks to the creator!!

This theme works really well for Pale Moon. Trying it also for Firefox.
