Firefox updated to 151.0 last yesterday and now the background of the search selection box has changed color to white from its earlier setting. I have tried a bunch of things but cannot find the CSS needed to restore it to what it was (it was overridden with an image). The image below shows the new, white, version, and what I am trying to do is restore it so that it is overridden with the same background image as the rest of the header. What is the rule needed to override the background of this new box (the box with the colorful "G" and downward caret)?

здравствуйте, опять проблема после обновления, сейчас 21:41 20.05.2026 по мск. буквально 2 часа назад все было хорошо но возникла эта проблема(поменялись цвета, те что светлее раньше были не такими, на фото в чате выше это видно). На втором скрине поменялось положение выскакивающей поисковой строки, она ушла выше на 20-30 пикселей

Сегодня обновил Mozilla FireFox до версии 146.0 (64-разрядный). После обновления в панели "закладки" (cntrl+B) появился ненужный мне цвет выделения только что открытой мною вкладки (смотри скриншот). Как поменять данный цвет на менее контрастный ? У меня включена "темная тема", цвет выделения - ядовито-голубой. Хочу изменить его на другой более мягкий цвет. Как это я могу сделать?

Today I updated Mozilla Firefox to version 146.0 (64-bit). After the update, the highlight color of the tab I just opened appeared in the bookmarks bar (Cntrl+B) in an unwanted way (see screenshot). How can I change this color to a less contrasting one? I have the "dark theme" enabled, and the highlight color is a bright blue. I want to change it to a softer color. How can I do this?

I use Firefox as it is one of the last good browsers that isn't chromium based. However, I use it for work and like a nice clean PROFESSIONAL look.

With the introduction of version 149, I see new cartoonish fox icons pop up all over the place. After a little research it appears to be Kit, the firefox mascot.

Let me be clear, I don't hate the mascot, he's cute. But that is not what I want in a browser. I find his appearance and lack of ability to eliminate him infuriating.

I try to run a firefox in a as minimalistic state as possible. Intruducutions of this character, make the browser feel cartoony and childish. Things I despise in an application. I know many people like him, but I would like the option to not have him appear in the application at all.

I was able to successfully remove him from the certificate warning page setting the flag: security.certerrors.felt-privacy-v1 --> FALSE.

However, I can't find other places to remove this nuisance. Take a look at the attached screenshot. Things like this are not welcome without a way to disable it.

Do you have any documentation or instructions I can use to disable this childish nonsense and restore an adult browser again?

Hi - Recently when I was on either my desktop or laptop I saw a notification that the sidebar would be going away. I can't seem to find any information on that now though. Will the sidebar still be going away soon? I for one would like to say that I enjoy that feature and would like to see it stay an option on desktops/laptops. If it does go away, how do we access bookmarks and synced tabs? Is there anything I need to do ahead of it possibly going away? Thanks in advance for your help!

since v150 came out ive been having an issue where i get a flash of white on start up if i have Homepage and new windows as Firefox home with a wallpaper... i have re-installed firefox and tested it as default and it still happens. seems the wallpapers have a delay till it displays properly.

In Windows 11, how do I add the Firefox icon to the extreme top left of its webpages?

When I switch tabs to Firefox, typically using Alt+Tab, I am often unsure at first which program I am in. I have searched Firefox settings, and googled extensively, and there seems to be no way to add the icon back. I believe that it was once there, but I am unsure of this.

Almost every other program places its icon on the top left of its pages. Surely it is possible to do the same in Firefox, which just has an empty space there.

(But I am wrong on the last point, because Edge, which I rarely use, also has no icon there. Surely Firefox does not want to share any problem that Edge has!)

Hello All, I'm just into Firefox. Struggling with two untidy bars across top of screen. Need advice to reduce this to one. I have my Win11 taskbar to the left on my PC. Can't we do something to put current open site in there?

I use Firefox to manage an online course. For some parts, I want to zoom in to see detailed diagrams etc. In other parts, I want to see at a glance a simple list of submissions. So I have 2 windows (with their relevant tabs) open. But when I zoom into the first, the other window zooms in, so I lose most of the listing. How do I set the zoom differently in the two windows?

Hello! Please report this bug to the developers. When I first launch Firefox after turning on my computer, the window title bar and buttons in the upper right corner (like "Minimize," "Minimize to Window," and "Close") sometimes disappear. If I minimize the browser via the bottom taskbar and then restore it, these buttons and the title bar appear. I'm using Windows 10 x64, with a screen resolution of 2560x1440 (scaled to 125%, but I don't think this has anything to do with the scale or resolution, as other browsers (Opera, Edge) don't have these title bar issues).

See screenshots at the links: https://imgur.com/a/Hbc9yvE (There are two screenshots: 1 - with the window title and buttons (as it should be), 2 - when the window title and buttons disappear)

I've noticed that if I let Windows sit for a while after turning on the PC (2-3 minutes) and then launch Firefox, the problem with the disappearing title bar and buttons seems to disappear. Apparently, Firefox doesn't have time to load properly after Windows loads, and if I launch Firefox almost immediately after Windows loads, the problem described above occurs. And when the OS sits for 2-3 minutes, Firefox apparently loads all its services and processes normally and then works normally, without this error. Firefox ver.: 150.0.3.

This bug was also discussed on the forum by some other users, and they are also experiencing this bug: https://forum.mozilla-russia.org/viewtopic.php?pid=818805

I am using Win 11, Microsoft Powertoys > Fancy Zones to manage the screen space on my 5120 x 1440 monitor. I also have System > Display > Multiple Displayers "Remember window locations based on monitor connection" enabled.

Any program I have besides FF will load up exactly where I had it last. FF shifts I am guessing 8 pixels to the right (or left, as this occurs if I close FF on the right side of the monitor.) If you look at the screenshots, the "opened at default" picture shows what FF looks like when I open it. You can see the xulstore.json file shows the screenX position is -8. If I manually type in 0, close out FF and reopen it, it will still shift back to the right a bit even with the .json still saying 0

How do I do one less thing when I turn the pc on and have FF open exactly as far left as possible instead of shifting over to the right?
