Troubleshooting

Gmail won’t open, with “Temporary Error”, and the Fraidycat extension doesn’t work:

  • There was a bug in Firefox 82 on Fedora. Upgrade to 82.0.2-3

Some websites display a white screen. When you inspect the console, the error “Uncaught DOMException: The quota has been exceeded.” is logged. (Seen in Fedora 33, Jan 2021)

  • I seemed to resolve the issue by clearing cookies and site data (Firefox → Preferences → Privacy and Security → Clear Data)
  • Test your Firefox’s local storage limit using https://arty.name/localstorage.html. My result said “5200000 characters were stored successfully, but 5300000 weren’t.”, so I’m able to store 5Mb-ish.

Webcam missing in Fedora 41+ and Firefox

  • Seems to be something to do with Flatpak/PipeWire
  • Use Flatpak to check camera permissions, e.g. flatpak permissions devices camera.
    • Even though Firefox isn’t a Flatpak app, it uses PipeWire to access your camera, which in turn uses Flatpak’s permissions store.
  • “Make sure that xdg-desktop-portal is installed with a specific portal backend for your desktop”
    • e.g. xdg-desktop-portal-gnome for GNOME
    • not sure what I should install if I’m using Xfce.
  • In Firefox about:config, set media.webrtc.camera.allow-pipewire to false - this might work until you can find a more long-term fix.
