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! : )

You used to be able to view all of your synced tabs from other devices by going into the toolbar menu > your profile > the device name but I went in today to pull a tab from my phone onto my laptop and it only shows about 5 tabs total. You have to click "see all # tabs" which then opens in the sidebar of the browser. I hate the sidebar, it just does not work well with my brain/visualization needs, and have been doing everything i can to avoid it. Is there a way for me to revert the display settings of synced tabs specifically? As I use them frequently enough that I am going to have to look into changing browsers if I continue to have to utilize the sidebar

Despite using the most recent updated version of Firefox (154.0.1--64 bit), I am unable to change the font size and font style in my emails. I currently use macOS, Catalina, version 10.15.8. I've selected Palatino, 24 pt. in the Advanced settings menu, but no changes take place. Please advise.

For some scrollables, v153 doesn't respect the Mac OS setting to hide scrollbars unless scrolling on page load. If that OS setting is adjusted after the page is loaded, then the page respects it again until refresh, so there's apparently some sort of race condition going on where it's not reading the setting in time before the page loads?

This is not a problem in v152. I downgraded back to v152 and it's working again.

This is not a huge issue but it is irksome. Why do the all the bookmarks in the toolbar justify left? Also, there are no UI options in the settings to change the justification. Most browsers center all the bookmarks in the toolbars. Surely this wouldn't be too hard to change, would it?

Since Firefox just added profiles, the app icon on my Mac now has a little heart on it to show which profile I'm using? But I'm the only one who uses this computer, so I don't need the profile icon. It just makes me think I have a notification every time I scroll over the dock. How do I remove this from the icon?
