I-Firefox Community Forum

I have an issue where the following operations with the "new" profile manager don't work: - setting up a new profile (about:newprofile in the new profile is just blank) (a new profile gets created though) - deleting a profile (about:newprofile is just blank) - editing any profile that is not the original profile (about:editprofile is just blank) (works with the original profile) - the select profile interface from the account or menu button is blank when opening it from any profile that is not the original profile

What works tho is calling about:profilemanager from any profile. From there any profile can be selected and switched to.

I'm using the Bazzite (Linux distro that is Fedora based). I'm fairly new to Linux so that could be a issue, the problem was there from the get-go though and since Firefox was preinstalled I don't believe I could've messed up much.

Firefox version is 147.0.4 Bazzite version is 43.20260211.0 (Kinoite)

Reboot doesn't fix these issues. Uninstalled Firefox with deleting user data, installed it again and same behavior appears again.

I also tried installing a Firefox fork (Waterfox). It had the same issues.

I would appreciate any help and would be willing to share more detailed date if it helps somebody help me.

The attached screenshots mostly show the UI that is not working as expected.

Some videos work perfectly fine, however for some videos audio lags behind the video. The same video file perfectly works in Chromium as a control test. Example file is MP4, inside was initially h264 video with AAC audio, for test I re-encoded video to be svt-AV1 with AAC / flac as well - no difference, audio still lags behind. Local players (mpv) and Chromium works perfectly. No plugins which can affect it - for testing disabled them all. I really try hard to like Firefox but this thing is a real bummer. Any ideas what can be causing? P.S. I tested both firefox compiled from source and binary package provided by my distro. Linux system if that matters.

I run Firefox on Fedora Linux (Silverblue). For several releases I've noticed that the reader mode only displays the Close Reader View, Text and Layout, and Theme options and nothing else i.e. no content.

When I run it in troubleshooting mode, it works. I've tried disabling all my extensions, deleting all my extensions,restoring the browser to default settings but nothing makes a difference. I'm always on the latest release (currently 147.0.3). I currently have multiple profiles, but it didn't work even before I rebuilt them. I'm out of ideas.

Any help is appreciated

Environment - OS: Omarchy - File manager: Nautilus (running as --gapplication-service) - Desktop portals: xdg-desktop-portal + xdg-desktop-portal-hyprland (+ gtk fallback) Firefox: latest stable from Arch repositories

Observations Only one Firefox process is running (pgrep -a firefox). Only one Nautilus process is running, but it receives two open requests, resulting in two windows. The issue does not occur in Chromium/Chrome, which opens only one window. Running xdg-open <file> manually opens one Nautilus window.

Portal logs show GTK being chosen as last-resort fallback, but system-wide XDG configuration appears correct.

Question

Is this a known Wayland/portal bug in Firefox? Are there recommended debugging flags or patches to trace the duplicate launch request?

Using Ubuntu 24.04.3 LTS with Firefox 147.0.3 (64-bit)

Firefox crashes when trying to access any banking website. Can get to the login page, but then firefox crashes and a crash report window comes up with quit or restart option. This has been going on since shortly after upgrading from 22.04 Ubuntu. Started with Firefox 147.0.1 and after upgrading to 147.0.3 did not fix the issue.

Started Firefox in Troubleshoot Mode and that works when going to the bank login page. Using Standard Theme and only extensions Windscribe - Free Proxy and Ad Blocker and DuckDuckGo. Disabled both and same result of crashing om bank log in pages.

I run Windscribe VPN through my separate subscription, but it doesn't matter if it is on or not. Banking websites (Keybank, Kinecta, Capital Group) still crash Firefox

Also crashes when trying to access Excellus BCBS log in page. Most other websites (news, sports, Amazon) are fine.

Searches on your support page yields ) results.

Please advise!!!
