Hello,

Suddenly some UI elements became color-inverted or almost completely black, such as the tab icons in the tab bar, the website icons on the New Tab page and some icons in the settings menu. Also, some websites appear to have this issue, but the Samsung website is the only one I found so far with this issue.

On the same day it happened I switched to an OLED HDR-capable monitor, so I assumed it would be related to HDR, but I played around with some settings and I'm not sure anymore.

What I tried: - hardware acceleration on and off - HDR completely on and off - default light theme and dark theme, no customs themes installed - all extensions disabled (I have no extensions that would influence graphics or colors anyways) - latest update already installed - nothing else changed in the Nvidia control panel as far as I remember

None of the above helped. Any advice on this is appreciated. Attaching some pictures with the issue. Using Windows 11.

Thank you!

Dark mode in Firefox has broken just now. The issue appears restricted to Firefox - all other elements in environment (Ubuntu/Cinnamon) appear to be operating correctly.

The elements at the top of the screen and some menu screens are now white rather than dark grey. Due to a neurological condition this causes near-instantaneous cluster migraines.

Is there a way I can fix this? Is there a way you can fix this? Is there a way to access the web without a browser? (eg through the text terminal)

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?

I left my computer for a while, and when I returned and took it off screensaver I started going through my emails when I noticed that the bookmarks on the toolbar are missing. The toolbar is present, and I toggled between only show on new tab, never show and always show a few times, but they're still missing. I even tried bookmarking two webpages, but they were not added to the toolbar. As stated, I have the bookmark toolbar to always show. Firefox just updated yesterday, 4/8/25 to 130.1.0, and I'm pretty sure that they were there this morning, but I can't be totally sure. I noticed my computer had updates available, so knowing updating it would not have any effect on Firefox, I restarted the computer while updating so I could also restart Firefox with a bit of a delay. I had also restarted it twice before without any luck. The only thing I did besides updating Firefox was enabled the sidebar, which I then turned off and still did not have any bookmarks in the toolbar. Any assistance would be greatly appreciated, but I may not be able to view and any responses or make the stated changes until Friday.

Hi Please could someone help me re-order my firefox toolbars. Previously I managed to arrange them in the order I prefer, but an update seems to have destroyed the order again, and I can no longer find the web page which explained how to do it. reading from the top, I would like to see: • Title bar • Menu bar • Navigation toolbar • Bookmarks toolbar • Tabs toolbar • Web content area

Instead I have • Title bar • Menu bar • Tabs toolbar • Navigation toolbar • Bookmarks toolbar (I even seem to have lost this now and don't know how to get it back!) • Web content area Thanks for any help that can be provided. Brox

My toolbar is visible when I click on the 'Open a new tab' plus sign at the top. But if I go to a site, either from a search or from bookmarks, the toolbar disappears.

I just (yesterday) had to delete profile, delete bookmarks, delete Firefox, install Firefox, in order to get it where it would save bookmarks again. The toolbar, prior to that, did NOT disappear when I went to a new site.

Please help.

Hello,

My experience with Firefox has been great for more than 15 years. However recently there's been a trend of adding new functionality without asking the user whether they want it or not. Moreover, some things cannot be disabled even if I try hard enough.

It was an unpleasant surprise to discover that "This time, search with" panel was removed without my consent, and is now replaced by an extremely inconvenient button. I firmly believe that this is not how UX design is done, and whoever made that choice needs to reevaluate their decision.

How can I revert this change besides rolling back the browser version?

The setting "browser.urlbar.scotchBonnet.enableOverride" did not help, it reverts to *true* on every restart. I have not been able to find any other settings, and I believe that this is not something that a user should do their research on.

Is there a way to affect this change?

Firefox mozilla recently updated, now the bookmark side bar has made the fonts dark on a dark background, now unreadable. How do I change the fonts back to white on a dark background?

I just updated Firefox and the bookmarks on the left become all black. Black font on black background. Unreadable. Before that, the font was white.

How do I change that ?

Thanks !

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

Hi Mozilla Community,

I am running Firefox on Windows 11 and I'm encountering a strange issue regarding the UI updates.

The Issue: My Firefox browser updates automatically to the latest version. However, my Default Profile is visually stuck on the old UI design. It does not reflect the recent interface changes associated with the update.

The Troubleshooting Context:

• I have verified that the browser itself is technically updated (via Help > About Firefox).
• The strange part: I have other Firefox profiles on this same machine. When I launch those profiles, they correctly display the new, updated UI.
• This issue is isolated strictly to my main/default profile.

Has anyone experienced this mismatch where the version number is correct, but the UI fails to refresh on a specific profile? Is there a specific fix for this?

Thanks in advance for the help.

Hi, is there a way to customize sidebar to move the controls to the top or bottom of the sidebar? With sidebar open there is a lot of wasted space with just 3 icons - settings, history and sideberry buttons. Not really an optimal situation.

Attached screenshot and another picture explaining where I would like to move the buttons. Either top or bottom of the sidebar is preferable than taking the side.

I turned on my PC after a long time, and it seems something about firefox has changed in the way I don't like. The logo to the extreme left of the address bar which shows "This time search with" options on left-click is annoying to the eye. Picture attached below. Is there anyway you can remove/disable that logo with about://config or anything else.

Using latest version of Firefox on linux.

Mozilla sidebar has been replaced by "Choose an AI chatbot to use in the Firefox sidebar." How do I undo this and return to Mozilla standard Firefox sidebar. Not at all what I want to do. Help
