Firefox Community Forum

Hello! My Firefox browser is currently in a state where all fonts/letters in the Firefox interface (bookmark bar, settings, about page, website name...) are replaced by undecipherable characters.

I've searched for similar problems already and tried so far the following steps to resolve, unsuccesfully...

• Opening the browser in Safe Mode / Deactivating all extensions
• Uninstalling and reinstalling Firefox

• Disabling hardware acceleration
• Trying on another profile




When I copy paste said text to another window (ex: Notepad, Chrome Browser…) it appears properly. And as you can see in the screenshots below the text in actual websites is readable -- only the browser's interface, setting, address bar... are scrambled.

Does that bug rings any bell? Do you have any other troubleshooting steps I should try to resolve this? Any help will be appreciated! : )

My browser window (not my private browser window, however, is starting to show text in web pages as a reverse Hebrew font. I can't figure out why. Translations are turned off and it happens on a lot of different sites. There is a screenshot attached. How can I make it stop!!!

Up until recently (apologies, I do not know which version) when editing userContent.css on Debian 12 in the ' Developer Tools ' I could just use CTRL+S to save my changes and all was well.

Now it appears to have forgotten where it loaded in the first place, because (when using the shortcut or the 'save' link under the name on the left) it just opens the user's home folder at its root level or ' ~/ ' ...

Is this a bug that I should raise at bugzilla? Or has another bug fix messed this functionality up somewhat?

This is the ' mozilla-deb ' / ' Mozilla Firefox Debian Package ' currently at version 154.0 which is usually updated weekly.
