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?

After the 8/5/25 Firefox update the internet is inaccessible on my laptop through the standard Firefox browser. The internet is accessible with MS Edge. Toolbar is set to always show bookmarks but none appear. Also, the browser's application's menu does not open to access options such as restore previous session, recently closed tabs, etc. I've restarted my device several times without it resolving the issues with the standard browser.

The Firefox developer version opened in command prompt safe mode (firefox -safe-mode), which is how this inquiry is being sent, but no bookmarks on tool bar or current page history from the standard (non-developer) Firefox.

I'd like to return to accessing the internet using the standard Firefox version with its bookmarks, history, etc. I am using Windows 10. Thank you.

My wife's Firefox was triggered from an e-mail link and in the process got updated to release 141.0 The result is that the tabs from the previous verion have not loaded. Can I still recover them?

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?

1. Close Firefox (FF) with some tabs open 2. While FF is closed the websites are updated 3. Open Firefox, tabs reopen 4. Go to tabs

Expected: Tabs should the latest version of the website (ie the page has been refreshed)

Actual: Tabs are showing the old, previous (cached) versions of the website and not refreshing to show the latest

User has to manuall refresh each tab to see the latest version of the page

Are other people seeing this issue?

Sorry for my language.

The latest versions of Firefox 141 (and 142 beta 1) do not allow the Windows taskbar to appear when I move the mouse to the bottom of the screen. This happens on Windows 10 with the auto-hide taskbar setting enabled. In previous Firefox versions, this worked fine (except for one older version where it briefly broke). I’m not running Firefox in fullscreen mode, and I have no modifications or themes that could interfere. I tested this on a fresh, clean installation of Firefox — the issue still occurs. After downgrading to versions 140 and 139, everything works correctly again. Interestingly, I also tested the Firefox 141 Release Candidate Build 1 from here: 🔗 https://ftp.mozilla.org/pub/firefox/candidates/141.0-candidates/ In that version, the issue only occurred in private browsing mode. Could someone please help me resolve this or confirm it as a bug? Thanks in advance!

Just updated my Mozilla Developer and it removed my bookmarks (the tab is visible but has no bookmarks, and restoring them from backup doesn't do anything) also the extention button is for some reason on the left side (it was on the right side) and the "+" button was missing, had to re-enable it (AND IT'S ALSO ON THE LEFT SIDE FOR SOME REASON)

Wtf happened

Hello,

Just today my UI elements went missing. For example I cant see my bookmarks on the bookmark toolbar, new tab sign disappeared. Addons are not the issue, I have refreshed multiple times with no addons installed. The bookmarks are all there, except somethings messing with the firefox. Started in safe mode, but in vain. Checked the group policy in the registry but nothing out of the ordinary. I deleted the policy, did a fresh install and still the problem persists. Tried switching hw acceleration on/off as well.

Any help is appreciated, I never had any problems with firefox before.

my extensions got unpinned and the new tab button is gone, the tab overview is gone, the extension button is to the left of the address bar, the back and forward buttons are to the left of the address bar, the back and forward button are swapped, WHY.

In the screenshot i pinned the 3 extesions i use again, they were unpinned before

When Facebook creates passkey Firefox asks for an USB to be inserted. I have tried to disable USB in the settings ("security.webauth.webauthn_enable_usbtoken","false"). But then Facebook just gets into a retry loop and I can't create the passkey. I use Windows 10, and USB is NOT enabled as an authentication option. I need to fix this as Facebook nags me (in e-mail) to create a passkey.

I'm using Firefox Developer Edition 132.0b2 (64-bit) and noticed that the only way to open a new tab is to click on the pancake icon and select new tab. The "+" icon in the tab bar is missing.

I also noticed that there is no way to reload the page (especially doing a hard reload). This is a major issue when making updates to websites and wanting to see those edit. Clicking in the address bar and then on enter will reload the page, but does not do a hard reload, so the cached version of the page is displayed, not the updates.

I wanted to open firefox and a new window for new firefox open but did not suggest me to sync my old bookmarks. instead it only asked me if i wanted to sync with chrome browser only. why was i not allowed to save old bookmarks before new firefox updated.

Hi y'all, when I use firefox DE, there is a bug in which the search bar overlaps with the tabs, after the new release. Is this because I use a custom CSS that reverts the tabs back to the old style? I would really appreciate it if I could still use the old firefox tab style without having my search bar overlapping with the tabs

Firefox consumes almost 2Gb of RAM with only one tab open. I find this surprising, and it's a major performance issue for me.

Do you have an explanation or solutions to reduce this memory overconsumption?
