Firefox Community Forum

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!

Firefox 140 I use Tree Style Tabs for my tabs, and have for a long time. I updated to 140 and now, at the top of the sidebar is "Tree Style Tab X". Clicking X closes Tree Style Tab and the sidebar. My question. Is there a way to not have Tree Style Tabs and the top of the sidebar, but return to "BookmarksHome" which was at the top previously? Appreciate any help or ideas.

I want to know what should I change to change between these two appearances. I tried to change everything with `browser.search` in about:config, but I don't see anything that changed it.

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 there,

Before (an update perhaps?), it was possible to click on a star icon located in the toolbar and it'd open the bookmarks like the bookmarks1 screenshot. Now, it requires to first click on the sidebar thingy, which allows to access the icons on the far right, which includes the bookmarks icon in question.

There's also another icon for bookmarks that can be put directly in the toolbar (bookmarks2 pic), yes, but it doesn't show all the bookmarks right away, it's not the same

So the question is: how do I do to get the Ctrl B Icon/shortcut directly in the toolbar, like it was before? I don't want to be obligated to use the sidebar when I have plenty of space left in the standard toolbar..

Thanks in advance!

Hallo, ich habe das problem das mein Firefox browser immer im Vollbild modus startet, das hat er vorher nie gemacht. ich kann es zwar über die F11 taste zurücksetzen aber das ist nicht gut, auch habe ich schon einträge in der about:config gemacht die das verhindern sollten was aber auch nichts gebracht hatt. Es wäre schön wenn man das problem beseitigen könnte.

Ichhabe auch schon alle pluging mal ausgeschaltet um es zu testen hat aber auch nichts gebracht. Vielelicht liegt es ja doch an Firefox selbst.

Es wäre schön wenn mir da jemand weiter helfen könnte.

Danke Olaf

If I don't use the custom adjustments in my Chrome css, seven buttons on that right side of the menubar are hidden, including the min-max close buttons.

This is problematic when I'm troubleshooting Firefox, and the css is disabled. If I want to close or take the browser out of max mode, I must move those buttons to the navbar, which has no such restriction accommodating those buttons, not to mention why is it necessary for that min-max close trio to monopolize 20% of the menubar. Waste of space. Inefficient.

I'm also curious why must that frame at the top of this sites pages remains persistent, and follows the user down the page, so that when you're composing, and accidentally (and all to often) touch one of those links, it get superimposed over the message, and you must move the cursor to the bottom of the page get rid of it. Not to mention, that frame shrinks the working area of the page about 30% vertically.

I mean, once you have already navigated to the destination page, and you're composing, how often/likely are you going to need to access that area?

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 all,

I just updated from v143.0.3 to v145.0 and once again some small breakages in my userChrome.css have occurred.

Things have become too rounded, including tabs, the URL bar, and the chevron button.

I've solved the tabs radius issue with the .tab-background {} selector.

However, my URL bar now has rounded corners. I would like it to be square.

Please see the attached images for before & after views of my URL bar.

I have this code in place...

#urlbar > #urlbar-background, #urlbar[breakout][breakout-extend] > #urlbar-background, #searchbar
{ border: 1px solid #a1a6b5 !important; outline: none !important;   border-radius: 0px !important; }

I've also tried this as a standalone...

#urlbar-background {
  border-radius: 0px !important;
}

But the above has no effect, although it did previously.

Is there a new way to control the radius of the URL bar?

Also, my chevron button became too rounded. Is there a new way to control that as well?

Thanks.

How can I disable the huge Firefox logo appearing on the top of the default home tab? It is enormous and takes up valuable space. Instead of having four neat rows of shortcuts which all show on a new page (like it used to be) that page looks terrible now. I have tried everything formerly recommended to others asking the same question (about:config, proton, etc.) and nothing works. My current version is 136.0.4 (64-bit). A workable solution would be greatly appreciated. Thank you.

The weather widget on the homepage sponsored by accuweather is missing a lot of major cities that were available before October 2025. They are available in accuweather, but for some reason my widget defaulted to singapore, and I can't manually select cities like chattogram / dhaka or even new york even though the are available in accuweather.

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.

My desktop has a line where you search. I do not have the full line. Missing view history saved bookmarks, home,print, settings screen shot. I have a new laptop two days old. The top of the home page look different from what appears on my older desktop. How do I get the full line. Also the very top of the screen says file, edit, view,History, bookmarks, tool and help. I do i get these features?

I have upgraded my Firefox to version 146 and I have a disruptive color of active bookmark in left sidebar. How could I change this color into moderate one - dark grey.
