I am on Linux Mint 21.2, and I just updated Firefox (141.0). Now, the bookmarks bar, toolbar, and the tabs (everything above the displayed page), as well as the menu, bookmarks menu, and sidebar, are in light mode even though I have dark mode set (They were dark before the update). I tried playing with the Dark Mode settings to no avail. My system is set to dark mode in general. Are others experiencing this? Is there some sort of fix?

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.

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!

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.

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?

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

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.

My emails used to display in date order but since a Mozilla upgrade they are now grouped as Today, Yesterday and Last Week. Is there a setting to alter this back to one list in date order please?

With the last couple of updates to Firefox (now running v133) on Windows 10 I noticed that there is a new search bar that overwrites the tabs on top of the Firefox window when I click into the URL bar, which is set up to be used for search. This began to happen recently but I'd like to know how to configure Firefox to do search like it used to, in the URL bar not a new search bar, and disable this new search bar that disorients me when it pops up and disappears.

Hi!

Is it possible to hide the address bar entirely when entering full screen. When I use Safari I have the option to hide everything except the page i am looking at, this makes reading manga really nice and distraction free.

Obviously I'd prefer to use Firefox so I was wondering if this is possible in settings or is a planned feature in the future.

Thank you for your help.

Hello all,

Ever since an update to Firefox from a few weeks ago, I have been having issues with white backgrounds displaying incorrectly in Firefox. I have attached two identical images from the NYT homepage: the first is a screenshot from Chrome and the second is the same exact image but taken from Firefox.

I have also attached another screenshot taken in Firefox from REI.com. You'll see that it's not necessarily just a white background that is causing the weird blue color. It also happens in products images being displayed incorrectly.

I figured this might be a Firefox website appearance setting, but I have played around with it and selected many different permutations and I haven't been able to solve this issue. I have also tried refreshing Firefox, using Firefox in Safemode, disabling all of my plugins/themes, etc. and nothing was fixed.

I am pretty sure this isn't a system wide issue or a monitor issue because these websites are being displayed 100% correct in Chrome and Edge. This is only an issue in Firefox.

Can someone advise?

Thanks,

DC

Hello Since few weeks (maybe on firefox 132 already, but surely on firefox 133) I observe issue with my firefox UI. While grabbing and holding tab (to change its position, move it on bar), whole tab bar gets thinner which realigns my whole UI. Issue is probably caused by my custom userchrome.css but I need it in current or similar form. Maybe there is some css specialist who can help me remove unnecessary parts of code?

My css is as follows:

.tab-background{ border-radius: 0px 0px !important; margin-bottom: 0px !important; } .tabbrowser-tab:not([selected=true]):not([multiselected=true]) .tab-background{ background-color: color-mix(in srgb, currentColor 4%, transparent); } menupopup > menu, menupopup > menuitem{ padding-block: 3px !important; min-height: 0px !important; }

root{

--arrowpanel-menuitem-padding: 2px !important; }
