elementaryos-firefox-theme VS blurclean-firefox-theme

for the theming in Firefox i currently use https://github.com/Zonnev/elementaryos-firefox-theme/tree/elementaryos-firefox-theme but I sometimes switch back to standard look ...in combination with tweaks it adapts the dark mode (the ubuntu repo firefox installed with apt)

You can try this Firefox theme for a better integration :)

I installed this theme: https://github.com/Zonnev/elementaryos-firefox-theme/tree/elementaryos-odin-firefox-theme

Yeah, this triggers me too. I remember having the same problem on KDE though, so it's most likely a Firefox thing. You can use this custom eOS theme for Firefox if it's bothering you enough GitHub - Zonnev/elementaryos-firefox-theme: This theme for Firefox supports all the window buttons layouts from Tweaks and it blends into the elementary OS user interface.

As in the title, I have weird black boxes behind the modals (e.g. bookmarks on the screenshot above) on Firefox. Initially I thought it was related to custom theme but after removing it and reverting toolkit.legacyUserProfileCustomizations.stylesheets, problem still exists. Any idea how to fix it?

By default no but thanks to the zonnev we have this: https://github.com/Zonnev/elementaryos-firefox-theme

If you are running the early builds of eOS 6 Odin you can install Firefox in there and add my theme for Odin. It's not recommended to install the Odin theme in eOS Hera since it won't look good because of double window borders and larger rounded window corners. For some reason in eOS 6 Odin, Firefox doesn't get window borders, so I added them manually with the style sheet.

This is a tweak of the original theme by Zonnev. I'm still working on some details, then I'll put the userChrome on Github as well.

Maybe some clues here?

Hi - sorry i'm kinda a newbie to this CSS thingy, i've installed a theme called blurclean - https://github.com/Filip-Sutkowy/blurclean-firefox-theme/blob/master/README.md, and nothing's changed. Have i done something wrong, or do i need to do some extra steps? I followed the instructions in the readme. There's a bit at the bottom that has some steps for KDE, but those don't apply to me as I'm running windows...

so i am trying to install this https://github.com/Filip-Sutkowy/blurclean-firefox-theme css theme but after doing everything nothing really changed (the search bar drop down is not black) but nothing else can someone plase help me

It is not working, I've already tried this https://github.com/Filip-Sutkowy/blurclean-firefox-theme/blob/master/components/window-transparencies.css
