Description

When running Firefox version 107 via firejail, I am unable to grant permission for the browser to use my microphone. I am able to hear sound through my speakers, but the microphone doesn't work.

Steps to Reproduce

  1. Run LC_ALL=C firejail /usr/bin/firefox
  2. Visit https://meet.jit.si/my-test-meeting
  3. Prompt to share mic (see list of built in and external mics)
  4. Pick a mic
  5. Click the microphone selection triangle (on the mute buttom)
  6. Firefox again prompts me to pic a mic
  7. In the Jitsi Meet microphone section, all mics get a red exclamation mark
  8. No mic works

Expected behavior

I expect to choose a mic and begin using it via firefox.

Actual behavior

No mics work and Jitsi meet marks all mics as non-functioning.

Behavior without a profile

When I run LC_ALL=C firejail --noprofile firefox it works as expected.

Additional context

The breakage happened after an upgrade and reboot. I can't be 100% sure, but my system is now running pipewire and may not have been running pipewire before. Or it might have been an upgrade to firefox 107 that caused the problem.

Additional details: When running chromium via firejail, the microphones work. When running with firefox-esr (102.5) it works.

Environment

  • Debian bookworm
  • firefox from experimental: 107.0
  • firejail version 0.9.70

Checklist

  • The issues is caused by firejail (i.e. running the program by path (e.g. /usr/bin/vlc) "fixes" it).
  • I can reproduce the issue without custom modifications (e.g. globals.local).
  • The program has a profile. (If not, request one in https://github.com/netblue30/firejail/issues/1139)
  • The profile (and redirect profile if exists) hasn't already been fixed upstream.
  • I have performed a short search for similar issues (to avoid opening a duplicate).
    • I'm aware of browser-allow-drm yes/browser-disable-u2f no in firejail.config to allow DRM/U2F in browsers.
  • I used --profile=PROFILENAME to set the right profile. (Only relevant for AppImages)

  • Does FF has PW support? AFAIK no (for audio, screencapture is a different topic)
  • Pipewire should be allowed
  • If it is pipewire the must be an about:config/env-var workaround.
  • What does about:support say about PW/PA?
  • What's the name of the mic in the permission pop-up?
  • FF 107, Fedora 37, pipewire-pulse works but I have a custom profile.

Thank you for the help!

Does FF has PW support? AFAIK no (for audio, screencapture is a different topic)

I believe that FF uses pulse audio, and that goes through /usr/bin/pipewire-pulse on a pipewire system

What does about:support say about PW/PA?

Audio Backend pulse-rust

What's the name of the mic in the permission pop-up?

Built-in audio analog stereo

Thanks in advance for any suggestions on things to try.

I'm beginning to think this is buggy firefox and/or jitsi meet behavior. I discovered that by clicking the microphone options in different orders I can get it to work. I don't think this is a firejail issue after all.

(Re-closing as "not planned" since nothing was changed in firejail)

Feel free to post any updates and to request to reopen if it seems that
firejail affects the issue.
