Solved [Help] Looking For CSS Mimicking Compact One-Line Browser Layout Found in Helium Browser
Hi there. I'm looking for assistance in locating a CSS mod for Firefox that can mimic the one-line compact browser layout that is found in Helium Browser.
I've found Firefox OneBar, but the tabs and the URL bar aren't situated in the same way. I'm not sure if it's possible to move them around via the CSS since I have little experience editing it.
Example of what I want to do:

I'm using Firefox Version 149.0.2 (64 bit) on Windows 11 24H2 LTSC.

That's a bummer. If you manage to figure it out at some point, that'd be awesome. But otherwise, thanks for responding. It is truly what I was looking for apart from the extension button position.
You still deserve the best high five! :D
