Firefox Nightly ver. 151.0a1 weird bug - Almost all menu backgrounds gone

[Andziaa]

So I noticed around 2/3 weeks ago that when I updated my version to the latest one suddenly I don't have backgrounds in ALMOST all menus, examples below:

Extensions:

Downloads:

Tab preview:

Even main FirefoxGX menu:

What menu doesn't count:

ONLY Right mouse click menu is normal:

I've tried using chrome and user.js folders from firefoxgx, but the issue persist even with clean installation. I don't know what is wrong...

Hi, Firefox nightly is an Alpha version, some changes arrive there in early state and could break the styles, I will checked if that issues arrived to beta version to see if in few days, with the next Firefox release version, the problems appear.

Various Files were updated to solve this issue for Firefox 151, not sure if solve all the issues in Nightly version.

Thanks for your work, for the moment whatever I tested, it was fixed!

I will test further these days and come back with final results
