Why can't anyone fix this issue? Every day I have to go to about:config, enter "mica" then change from false to true or true to false to get these buttons to show up. It's ridiculous. I am currently using Firefox version 146.1 on Windows 11. Also, please note if I change the windows widget to true these buttons show up and are usable. The next days I have to change the windows widget to false and they show up and are usable so they work whether or not the widget is set to true or false. The problem is having to change the setting DAILY. I should not be having to do this.

Firefox on Windows 11 has suddenly and without my apparent action started automatically hiding the tab bar and the address bar to give all the vertical space to the current tab. I do not like this (I have big monitors and I want those bars always visible)

How do I turn this one and why did it turn on in the first place?

Thank you for having the Q&A facility.

My bookmarks side bar font changed color from black to white, how do I get it back to black?

I can't seem to find where the font color is available to change colors.

Running version 146.0.1 No new extensions. Recently, when I hit ctrl+b to bring up the bookmarks sidebar, it opens but doesn't display the bookmark correctly. (image #1) The sidebar opens, but everything is whited out. The same thing happens when I try to open the history sidebar, except that the urls kind of show up. (image #2). Also, when I'm on my homepage, there's a white line on the left side that I can't get rid off. (image #3) I also tried refreshing firefox, but that didn't do anything. Does anyone have an idea what may be causing this? Thanks

The entire window of Firefox has an abnormally low resolution, makes the entire browser seems blurred. This issue occurs after I upgrade firefox to 146.0. I've attached a screenshot, and you can see the Firefox window has lower resolution than the wallpaper and task bar.

After the last Firefox update (146.0), my bookmarks bar only shows thumbnail images. The descriptive text which was previously black text on white back ground now appears to be white text on white background. (Whether my system is set to light theme or dark theme.) This happens on all of my Windows computers (both 10 and 11). How do I resolve this problem?

Hello, I just updated to Firefox version 146, and now the bookmarks and history in the sidebar are no longer visible because the background is yellow-green and the text is white...so, invisible!

I hope you will fix this quickly with a new update, as it's a real problem.

Thank you in advance. Sincerely,

Hello,

Since update 140.0, the side panel is dark (no problem), but the text is black instead of white!!! Which makes reading black on dark is very complicated... Could you fix this problem with a new update? Thank you so much in advance.

146.0 (64-bit) Windows 11 December 11, 2025 Turned on computer this am, Firefox webpage popped up telling me about what is in it's future but now my side bar is black print on really dark background. Help!

It looks an update occurred but now my bookmarks Column has a white background with white type. I can't read anything there because its all the same color how do I change the background to black?

Hello,

I just set up a computer with Debian 13 'Trixie', and I downloaded and installed the latest Firefox for Linux (version 145) from Mozilla's site.

Then I noticed at first that it wasn't following my GTK theme. Then after testing a bit, I discovered it would respect only themes with names that end in "-dark". I've taken some screenshots and attached them to demonstrate the problem.

firefox-esr from Debian's repositories didn't have this problem. But also, I've got another computer that still has an older distro (Debian 11) installed, and I'm running the latest firefox 145 on that too, and it always respects my GTK theme regardless of whether its name ends in "-dark". So, perhaps this is a GTK/GTK4 problem or something?

Does anyone know about this issue, can anyone help? I would really like Firefox to respect my choice of theme regardless of whether the theme's name ends with "-dark" or not.

I don't remember when it started but text that wasn't underlined before such as: Names of shortcuts in new tab view Titles of YouTube videos on home page, and recommended while watching a video (not on the video itself) Reddit titles and usernames (old UI)

I have checked settings as best as I can and tried disabling all extensions but still have the issue.
