Firefox Community Forum

Firefox used to have my background colors, and on the latest update, my pull-down menu and tabs are robin's-egg blue. I can't figure out how to get my colors back, and I hate that color.

How the hell do I get back control over my colors?

I have a Firefox icon on my Windows11 desktop, Start, and one on the taskbar. If I click one either the Firefox icon on the desktop or Start I will get another icon on the task bar and I can do this over and over on my personal desktop getting many Firefox icons.

I just purchased a new Dell Windows11 desktop and have installed Firefox. I set it up just like my personal desktop and have icons on the desktop, Start, and taskbar but every time I click the Firefox desktop or Start icon I don't get a separate icon in the taskbar but they pile up behind the original Firefox on the taskbar. If the cursor hovers over the Firefox icon then I can see the multiple Firefox homepages that I generated.

I have searched for an answer to this problem but have been unsuccessful. I would really appreciate some thoughts on this issue. Firefox has been my one and only browser for many years and I love it 99% of the time, just not this one time. :-) Thank you in advance. Chuck Hall

Is there a working way to move tabs to bottom currently?

This was working until the latest Firefox update and I do not specifically remember how I had changed it last time but I believe it was via the about:config settings page but I no longer see such an option there. I tried achieving this via 3rd party plugins/extensions for Firefox but not a single one worked for the current version of Firefox. I even tried using the UserChrome.css file, as I found an article about this in the forum but it did not work either.

In the attached screenshot I have shown what I have currently and what I used to have and wish to set again if possible.

OS: Firefox version: 136.0.4 (64-bit)

A folder on the bookmarks menu that stroes individual bookmarks, fills half the screen of a standard 1080p screen with totally empty white space.

The padding in between each and every single bookmark, in any place that can store bookmarks, will be filled by at least 3 or 4 mm of empty white space. Between every single bookmark.

This is a huge amount of completely pointless scrolling.

Do you have an RSI? No?

Good for you. I, sadly do.

Has there been a fix for this cos the chrome folder .css "fix" is not working for me.

If i cant solve this i am going to change browsers. I dont care. I love Firefox and used it since the netscape days in the 90's, but am not going in for another surgery since you people insist of giving people more RSI's.

These icons appeared recently in my Firefox browser I can't remove them. The only recent changes included uninstalling SuperAntiSpyware after finding that Microsoft PC Manager is a better option, which has performed excellently without issues.

Additionally, a free VPN (Proton) was briefly used from the Firefox browser without installation, but after finding it complicated to set up, it was deleted. A few hours later, I noticed the two icons as the windows were misbehaving and they are causing a slowdown in the PC's performance. They do not seem to be add-ons or extensions.

How do I remove the icons and return to the previous performance?

Hi everyone!

Since last update (136?) when I open a page with a video in a new tab, the width of this tab is very small! Almost half my current tab.

(I don't have another example but does this have anything to do with any "media" on a page?)

I have the width set to 152 for years...

When I play a video, the current tab is reduced. Pause= normal tab. Play= small tab. Pause= normal tab...

"browser.tabs.tabMinWidth should have been adhered to."

I just completely reinstalled Firefox: still the same.

What can I do, please?

'bold textHow do I remove the recent browsing button from tab bar. I get shaky hand sometimes and this annoying button messes Firefox up. It is the most annoying new feature ever.

Hello all:

Just downloaded version 140 and ran into an immediate "visual/appearance" problem with regard to the background color(s) of the sidebar bookmarks view. Many themes now have totally dark sidebar colors and not readable (see screenshot image upload with this posting). I always have my bookmarks (almost 1200 of them) displayed in my sidebar, and this is the first time an issue like this has arisen with a Firefox update.

To remedy this scenario, I must use very light colored themes that have a white background when you bring up the sidebar bookmarks. If not, everything is totally dark and unreadable.

Any ideas or help on this one?

I was customizing my background by loading a picture. It's adult in nature. It should be my computer in my in my private home. When something amazing started happening. If I load ANY image with a naked woman on it After a few minutes Fire fox auto removes it. I have done this 30 times. I use ANY fire fox picture it's fine stays there forever. Load ANY picture with a naked woman on it and poof 2 minutes later it's gone. So please can you explain to me why whats claimed to be the most private and secure browser around is censoring me in my own home about what backgrounds I can have? I find this highly disturbing. And I am quite serious I have had them removed at least 30 times. I'm 56 y/o If I want a naked woman on my background it should be my business not fire foxes. Also no chrome is not doing it. neither is windows. It's Firefox removing them. Any explanation would be nice.

1. My left-hand sidebar contained about 150 URL links, mostly not bookmarks. I have used this constantly for the last 10 years to access desired websites. 2. After installing 149.0.2 this sidebar with all links disappeared when Firefox was restarted. 3. I tried several suggested remedies such as changing profile or settings on General or Home tabs. None of these were successful. 4. I have seen a portion of my list twice, enough to believe the entire list is stored someplace. It displayed in a box on the Firefox page, but I cannot remember how I produced this list.

How do I get back to having a sidebar full of links?

On Arch Linux with the latest version of Firefox, the interface elements turn black due to a theme loading failure. 'This issue persists even when using the default theme.

Going to Settings and disabling the theme (which automatically falls back to another theme) resolves the problem.Re‑enabling the problematic theme does not reproduce it immediately. However, the issue reappears after restarting Firefox.

Hello,

In the latest update I got it made everything into rounded corners. The Tabs and Settings windows as an example. How do I undo that?

I checked thoroughly in the appearance settings and dont see a way to do that. I specifically switched my entire world over to Firefox to get out of the rounded corner UI world only in time for this switch to happen. How do i undo it?

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.

macOS Tahoe, Firefox 152.0.3 macOS settings include "Appearance - Auto"; i.e. system switches from light to dark at sunset. While the "top area" (tabs, address bar, bookmarks bar) of Firefox follows this - some of the pages themselves do NOT???

I found this website which was at top of the search results. I tried to follow it, but it seems to be badly outdated in certain key respects: esp wrt a setting called "ui.systemUsesDarkTheme" in about:config. I set this to "True", but may have screwed this up!! First question: Should I "reset" this somehow?

Finally: To get at the primary question, there are two "sub-questions" that may explain my confusion more clearly:

1. Is there no ***simple way*** to get Firefox & webpages I view to follow macOS Light/Dark appearance?? What are the CORRECT steps?

2. Do individual webpages have the ability to "decide for themselves" whether or not they will adhere to the system light/dark settings. This may well be an officially "stupid question", but while "most" webpages remain "Light" (including this Support page), a few pages appear dark.

Thanks, ~S

When uploading a file to attach to another app...the upload window opens up in dark mode. I don't like this and I did not change anything but it happens repeatedly. i have checked all options in settings to make sure the light mode is checked. Why is this happening. i did not change anything. Please advise. Thanks

Those instructions don't work and I'm sick of spending so much time on this problem these days.

Now thinking it happens after an update, which is a problem because they seem to come just days apart. None of the solutions offered works because right-clicking on the top doesn't do anything. Nor does going into the settings in the app on my laptop or online. I've downloaded and installed the latest version of Firefox more than once in the recent past. I've also shut down my laptop and rebooted. Nothing works. It's extremely annoying not to be able to access the features that I use *all the time*! day. I'm using a laptop with updated Windows 11.
