This is amazing. The features of this just scream awesomeness!

Using Beta 89, and can't stand the all grey tabs/background. Why Mozilla would remove the color matching for Windows is stupid. At least I can make it as if it was 88. Only four stars since I can't seem to figure out how to make the right click background white instead of black.

currently not working for new firefox proton design

My small issue is in the customization page. On my laptop screen (1440x900), I couldn't click Saved Themes tab due to the element (popup preview) in front of it.

yea
