Yuk they made it look like chrome and I hate chrome
Firefox was its own individual look and feel, now they are going down the same path as crappy Microsoft Edge and Chrome Noooooo.
Gone all white and Plain I don't like it.

I wouldn't be surprised if statistically people preferred every interface to look the same, people can be very averse to change. This new interface makes almost all of my custom themes look like s**t. It's mainly because of that all too thin rectangle around tabs, but also because address and search bars now use a default teal highlight colour. It's possible that those two can be modified, but it's unlikely that some older, less popular themes get updated.

Whole bunch of tweaks, etc., here: Firefox... taming the beast !


Short version...

browser.proton.enabled = False
browser.aboutwelcome.design = False
browser.proton.contextmenus.enabled = False (bookmarks spacing)

Disabling proton breaks the hamburger menu, its position is too far in the right at 1440p. I tried restarting the browser and restoring a default theme.

What is the "aboutwelcome.design" for? I don't have that entry at all.

I'm using Firefox 89 on Linux and it seems to work well I did have to disabled hardware acceleration in the browser performance settings.

It's really different and I guess we'll have to wait and see what the days and weeks ahead bring with Firefox 89.
