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)

Firefox on my mac has been acting buggy lately. The last time I quit and reopened it, all of my windows and tabs were gone. there is no restore previous session available and the recently closed tabs and windows options are grayed out. How can I restore?

I got a new PC and tried to sign in to my FireFox account to synchronize. But, foolishly, I ended up resetting my password! Don't know why did that, as I was able to locate my password stored elsewhere. I think this action erased all my data in my online profile & I cannot access my account data (bookmarks, user IDs & passwords) online.

Since my data was still in my old PC, I followed the directions for finding my Profile folder. I copied the folder contents to the Profile folder in the new PC. This has not worked.

I realize I wasn't supposed to copy the entire folder contents, which could be the reason why it's not working. Also, the profile folder contained a large amount of data (3 G). So, it's possible that not all files have been transferred correctly.

Please help me!

Thank you very much! Madoka

In May 2025 all browsers should have removed the default styling for the h1 element when it is nested in a sectioning element (article, aside, nav, section). I went into Firefox Dev Editions user-agent style sheet and noticed that the styling for nested h1 elements is still the same. I'm wondering why that is the case, since I was under the impression that all the major browsers had completed make the necessary adjustments at the end of May 2025.

`StartupWMClass=firefox-aurora` in `/usr/share/applications/firefox-devedition.desktop`, with actually `firefox-dev` for opened windows.

Version: Ubuntu 25.04, GNOME 48, firefox-devedition 143.0b2.

When I select Dark Theme, I DON'T wanr to see this. I just noticed this on my Linux Mint desktop machine tonight when I logged in. I also have Dark Reader installed and it isn't affecting ioit eitherit either. Make this go away. It burnsssssss!

I am aware, there are far more serious issues on our hands, but someone please fix this naming on the FTP server?

Idk maybe adding enough zeroes to make the release number 8 or 10 digits long.

0000000005 instead 5 0000000028 instead 28 0000000077 instead 77 0000000131 instead 131

The current order is like 131, 28, 77, 8.

I'm using Firefox 141.0 on OpenSuse Tumbleweed with KDE and Wayland. I'm using Firefox with two profiles: work and personal - which is (usually) awesome, until suddenly it's not.

Then, one or both profiles seem to become corrupted, and closing firefox, opening it, choosing either profile just hangs forever. My old tabs show up, but clicking on any tab, for any site, just hangs forever, and no page is ever loaded. Sometimes restarting helps, but sometimes not. Sometimes restarting 2 or 3 times and then suddenly it will work. But normally, I have to just delete all my profiles, and re-create them. Fortunately everything is synced with Firefox sync. Then everything will work wonderfully for a bit - although I have to re-login to everything.  :-(

Any ideas? This is a huge pain and productivity killer. I really love firefox, but this sucks.

Hello, I just used the Firefox 141.0 (aarch64) wizard for Raspberry Pi OS 1.0, to import bookmarks from Brave, however the wizard said 0 bookmarks imported.

I also manually exported and imported the bookmarks.html file and the latest bookmarks aren't appearing at the top. It seems the bookmarks are nested in some bookmarks directory by default. I'm confused?

Also I tried a manual import several months ago but same issue about some strange nesting structure rather than simply appearing at the top. Now I'm really confused and worried I'll lose my bookmarks as there's about 3 version in various nested structures. Please help just make an easy move to Firefox.

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 use the flickr website many times during the day without issue, unti now. When trying to login this time I get the message shown in the attached image. I have gone through all the usual procedures, clearing cookies etc, including starting Firefox in safe mode, but still the problem persists and I am now at a loss. As a test, I even installed the Chrome browser and I was able to log into flickr with no problem. I have a laptop running Window 11 and the latest Firefox and the problem is the same on that - no flickr login.

Thank you for your help

I've seen the other support requests on this from the past. Setting " print.tab_modal.enabled = false " doesn't seem to work now (Firefox for Mac 141.0.3).

Is there any (2025) way to default to "print with system dialog" rather than having to choose the link off of FF's dialog every time? It makes printing to PDF (which is 95% of my "printing" from FF) needlessly tedious.

Hello team,

I tried searching for a solution for the problem I'm about to describe but unfortunately I wasn't able to move forward.

I am running Firefox 141.0 version on my Macbook M4 Pro. The refresh rate of the display is set to 120Hz, but I the scrolling and interaction in the browser feels like it's on standard 60Hz refresh rate. When I compare it to Safari/Chrome it's not as fluent as it should be.

Am I missing an existing option that could be changed or is it something available at the moment?

Thank you, Arsen
