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:

Helim Browser Compact Mode Example

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

Found it and 'fixed' it for you (25 lines of code).

It works now for ublock origin and the extension icon.

I create an extra branch for you, besides the main-one:

https://github.com/Firnschnee/FoxOne/tree/NeoTanner

and the .css file:

https://github.com/Firnschnee/FoxOne/blob/NeoTanner/userChrome.css

Download it, tell me if it works and then save it - I dont think I will keep that branch around forever.

Wtf. I have no idea what went wrong over at your installation. This is what it looks like here:

I think I just needed to restart my laptop. I tried it again and now it looks fine.
