Firefox 96 hard-coded buttons?

the latest firefox 96.0 upgrade has fixed buttons while using the titlebar-less mode. The previous versions upto 95.0 used to follow the set gtk themes for the minimize, maximize and close buttons, but in the latest version it stopped following my set theme and just defaults to using windows like buttons even tho I’m using breeze theme. All other gtk apps seems to work fine and use the breeze buttons. all except firefox.

Can anyone help me fix this? I want firefox to follow my theme and use breeze icons for the titlebar (tab-bar?) buttons.?

As you can see the pamac, which uses gtk, is using breeze buttons as it should but firefox is not.
I am suspecting maybe firefox switched to gtk 4 and that might be the issue but I can’t find any documentation for it.
Can anyone please help me here.

No, it is still gtk3.

Have you tried right-clicking the toolbar, choosing “Customize Toolbar”, and then checking or unchecking the Title Bar option at the bottom left?

I did and then it starts using plasma’s window decorations, which works fine but honestly i think that’s a waste of screen space. Putting the buttons in the tab bar
was one of the best changes ever made to browsers and I want to use it that way. But using it with the buttons in the tab bar will make it use the ugly windows buttons regardless of the gtk theme set. It used to work fine in 95 and it still works fine if I downgrade it.
But downgrading it locks me out of my profile and forces me to use a new profile without my data. So I’m stuck in 96.

Actually, it isn’t. When the buttons are in the toolbar, then that means they are under control of the application ─ which is called “client-side decorations” ─ instead of under control of the window manager, and this in turn means that if the application crashes, then you cannot use those buttons anymore for closing the window.

This only happens when you use any of the built-in firefox themes except the system theme. Go to Settings > Themes and set it System Theme

I’m using the system theme on my Firefox 96 and the buttons are the breeze buttons on my end.

I tried, but … there is no system theme there anymore. I don’t know where it went. Also I’m not using any of the built-in firefox theme but my own. changing theme doesn’t fix it. I tried changing to several themes, they do not affect the buttons at all. Thank you for your help anyway.

edit: IT WORKED!!! THANK YOU! I couldn’t find the system theme earlier cause I have a huge list and i’m stupid. It uses breeze buttons only with system theme. It is kind of weird tho cause it worked with other theme created by users before.
THANK YOU SO MUCH!!

(sorry, it’s in Danish)

See this thread then. You might want to edit the userChrome.css file:

Yes they work on system theme, thank you.

I’m sorry if it’s a stupid question but where is the userChrome.css file?

kFind couldn’t find it.

First of all you don’t need to do any of that now if the issue is fixed cause because playing with this file (generally) causes a mess!

It is just a additional method of customizing firefox using a set of pre-defined rules.

This is how you create it
Open about:support

Click on "Profile Folder" -> "Open Folder" (or directory)

Create a sub-folder named "chrome"

Change into the new folder

Create a file named "userChrome.css"

Add some rules #https://www.userchrome.org/what-is-userchrome-css.html

Restart Firefox
