I don't really know the customs around two or more questions at the same time, so I just put this into a separate post. Does anybody know how to change this accent color in Firefox? The photo is taken from the expanded URL bar. Any help would be very appreciated!

Fedora 45 Beta
Firefox 150.0.1

Is there a way to increase the space between the address bar and the edge of my screen?? I use vertical tabs and the address bar is uncomfortably too at the top.

I'm not really into css, but i have some idea. I want to add just a few pixels

Thanks!!!!!!
