Bringing sexy curves back to Firefox Photon.
Because all you sexy Firefox users deserve something sexier than ugly, blocky square. (Who wants to be square, right?)
Since Firefox 57+, the only way to customize your browser UI is through userChrome.css. Learn more here.
Rough instructions:
- Go to your Firefox browser, type
about:profilesin your url bar. - Under the profile that is in use, open the Root Directory folder.
- If that folder does not have a
chromefolder, create a folder, name itchrome. - In the
chromefolder, create a file nameduserChrome.css - Copy and paste the code that matches your Firefox theme. Dark, Default, Light
- Restart Firefox and enjoy some sexy curves :D
Fret not! Please create an issue and I'll see what I can do.
