I'm using W11 & Firefox/Mozilla 'Version 146.0 (64-bit)' in ‘Dark Theme’ - my sidebar bookmark in use is now 'highlighted in BRIGHT blue' which is VERY ANNOYING - can I get rid of this feature? Is there a way to adjust the highlight color/intensity? Please let me know. If there is no adjustment possible, please take care of this in your next version. Thanks, John

After the most recent Firefox update, my background colors are black, they were white before the update. I have attempted to change the settings for the background, no improvement.

I contacted the place that put my laptop PC together for me, one of their service techs spent close to an hour attempting the sames steps I tried. Did not fix. They said if they learn anything, they'll contact me.

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.

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.. )

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?

After the most recent update, the Home Page does not show the minimize, maximize, and close buttons, when I first open the Firefox Browser. I can click task bar / show desktop and then maximize the Firefox Browser. Once I do that, the forementioned Home Page buttons appear. It seems that a fix is needed for this glitch.

Hi, I updated to Firefox 146.0 this past week and immediately noticed that the UI elements (scrollbars, sidebar, tooltips, etc) are once again in dark mode; the main websites window and the firefox settings remain in light mode (as set by my user preferences). I've been using browser.theme.toolbar-theme and browser.theme.content-theme to force light mode of all UI elements regardless of theme and as of this last update they have stopped working (editing them to any value of 0,1,2 does not make a noticeably change to the UI). What internal setting changed to stop firefox from using the browser.theme.(etc) settings and what can I edit to get them back? Thanks, Bre

As the title says , im really hoping for a small change that will happen from Firefox team or an addon , since i started using vertical tabs it was the best thing ever happen. however im really just hoping to have the option to increase the icon size of the tabs, i usually just have the icons showing without the name of the tab thing, but my only need is just to have the ability to increase the size of the icon tabs thats it

My Bookmarks Sidebar is now displaying with white lettering on a very light gray background, making it almost impossible to read. How can I change either the font color in the sidebar, or the background color?

The scrollbar slider isn't displaying correctly. If I grab the screen, zoom in, and look very carefully, it is possible to see that the slider is a very slightly different darker shade of grey to the rest of the scrollbar, but it's almost impossible to see, so something is clearly not working properly here. The scrollbar should be highly visible as it's the most often-clicked control of the entire browser.

When using vertical tabs and having bookmarks toolbar only visible on a new tab, there is this behavior where if you are on a website (bookmarks toolbar not visible) and then open a new tab, the vertical tabs move because they need to make space for the bookmarks toolbar. Would it be possible to make it like it is, for example, in Microsoft Edge, where when you open a new tab, your vertical tabs do not need to move because the bookmarks toolbar is as if off to the side a little bit, so the vertical tabs do not need to provide extra space for it? My hope would be for the bookmarks toolbar to be next to the vertical tabs, not above them.

Not a question, but I am vying for your "Least Important Problem of the Day" award. Mozilla makes great products. And,

The recent new "window fades away" when closing Firefox (or upon saving a file) is weirdly annoying and unnecessary imho. Obviously not a deal breaker, but I'd prefer if the window just closed. I don't need to wistfully watch it fade away. Thanks for the chance to offer input. Why am I even writing this.

I sure hope my bookmarks don't disappear like folks I'm seeing here today.

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!

Firefox for Windows just updated to v146.0. Now I seem to have an extra bar under my toolbar and address panel. How do I remove it? I can't seem to drag it in the menu customiser.
