Firefox Community Forum

I have issues discerning where each of my desktop windows are. To help with this I use gtk.css styling to add a border on all of my desktop windows. For some reason, Firefox does not draw this border.

Is there any way to apply a border around the Firefox window?

I was able to get a border around the navigation area of the browser by adding a userChrome.css file but I don't see any way to do the same thing for the whole window.

Can this be done in userChrome.css? Using gtk.css styling? Any other setting or file?

I am running Firefox 155.0.1 on Ubuntu Linux 26.04.1 LTS using the Gnome 50 desktop.

From time to time, sometimes after Firefox updates, I get unintelligible characters on tabs, search bar on Firefox. It gets more frustrating because the issue extends to the Settings menu, so applying the fixes I see on the web is definitely not easy.

I am on macOS, a newer chip and below is what I tried.

Restarting Firefox Checking the library for duplicate font installations. Disabling the extensions Starting Firefox on troubleshoot mode Uninstalling/reinstalling Firefox Uncheck Use recommended performance settings (blindfolded by using the search panel under Firefox Settings) Uncheck Use hardware acceleration when available (blindfolded by using the search panel under Firefox Settings)
