The UI font on Firefox UI appears to be corrupted. See screenshots attached.

The app was installed recently and not used much. When I launched it today the font appears like this. No other apps are affected.

I only have a handful of custom fonts and none overwrite any system fonts.

Firefox 114.0.1 https://assets-prod.sumo.prod.webservices.mozgcp.net/media/uploads/images/2025-02-11-10-08-03-3077a4.png Firefox 135.0 https://assets-prod.sumo.prod.webservices.mozgcp.net/media/uploads/images/2025-02-11-10-08-57-f4934b.png

After upgrade from Firefox 114 to 135, toolbar has changed and is almost unreadable. What can I do?

I use Windows 10.

Hello there,

During my quest of trying to get macOS and apps to look more like I want, I haven't found any answer online on how to modify the rounding of Firefox corners to be square. I have also heard that Firefox has a known bug of not respecting system appearance, so I have decided not to mess around with important system files. So my question is: What would be your recommended way to square the window corners for macOS?

The weather widget on the homepage sponsored by accuweather is missing a lot of major cities that were available before October 2025. They are available in accuweather, but for some reason my widget defaulted to singapore, and I can't manually select cities like chattogram / dhaka or even new york even though the are available in accuweather.

Firefox has just introduced wallpapers for browser home page. I cannot get it to work. It's either cropped too small or pixilated, is there a setting I need to adjust, or a particular image format? So that it looks ok.

why did the newest firefox update change my bookmarks to black text over slightly less black background? and where is this 'easy to find' setting found in the quagmire that is settings?

Yesterday morning i had sidebar bookmarks. Then when I turned my desktop back on in the evening it was gone. I have a few "tabs" on top which I do not like at all. I can't find my bookmarks, other than recent ones. How can I get my bookmarks back on the sidebar? I need some sort of fix please, to get my bookmarks back on the sidebar where they were.

Hello, Since the update on 24 June 2025, bookmarks are displayed in black text on a black background. Is this normal? If not, how can I resolve the issue? I had set it to dark mode, but even when I switched back to light mode, nothing changed. I would appreciate help from the community or Mozilla if anyone has a website address to contact them. Have a nice day.

Latest FF update changed the background of my bookmarks toolbar to a dark gray.. And made the text BLACK! Practically unreadable! Previously the toolbar was BLACK (Real 000 black) and the text was white.. As is my desktop.. Much easier on old eyes this way.. Is there a fix for this? I couldn't find one in Settings.. I've been using Firefox since the early days and XP.. I'm too old for more learning curves.. Help! (And thanks for wading through what's turned out to be another epistle.. Young men dream dreams.. Old men tell stories..It's an old guy thing.. )

The book mark side bar has become very dark ( BLACK ) since the your latest update and is not really visible. How do i change the writing so that it can been easy read ( WHITE )
