You can ask here and they will let you know if you need to open bug. https://bugzilla.mozilla.org/show_bug.cgi?id=1705501

Make a new account on another website just to ask mozilla to stop messing up their browser with every update? Thank you, but no. I will wait until somebody posts an obscure setting someplace, apply the solution, and then block future updates altogether.

Sorry but I am just so very tired of this shit.

Oh this is just getting better and better. Now when I right-click my bookmarks via bookmarks -> other bookmarks to open up in a new tab, or window -- it's all greyed out.

This browser has been good for many years but it's turned to absolute dogshit. I'm seriously considering switching browser and never looking back unless there's a fix for this crap.

What in the flying fuck are the developers thinking, seriously? Why force all these useless changes and not let people revert them?

Menus can either have a light theme (dark text/light background) or a dark theme (light text/dark background). This is selected automatically based on the theme used on the toolbars. Specifically, it is determined by how dark or bright the text of inactive/background tabs is.

If you want to override the built-in logic and force the menu colors, you can use the unofficial/community-supported approach, which is a userChrome.css file. For example, these rules will give you light-themed right-click context menus:

/*** Color the menus (black on white) ***/
menupopup {
  --menu-color: #000 !important;
  --menu-disabled-color: #555 !important;
  --menu-background-color: #fafafa !important;
  --menu-border-color: #333 !important;
  --menuitem-hover-background-color: #ddd !important;
}

Are you interested in more information on setting up a userChrome.css file?

I appreciate your response, and I do not mean this as a personal insult towards you -- but that is an extremely dumb approach by Mozilla, as light theme just plain blinds me, and dark theme is just too dark. I know for a fact that I am not alone in feeling this way, and them just providing us with a literally black or white solution is extremely narrowminded of them, and plain messes up many good looking themes for the browser. I am just so very disappointed in them. With that said...

...thank you for your response. I believe I have set up a userChrome.css file before to override previous dumb changes by them. I will try adding the code you provided me with. If it works, I will mark your post as the solution and require no further assistance.

Again, thank you for your time despite my attitude.

EDIT: Nevermind, figured it out. Thank you!
