Question

Meta Quest Link App causes Firefox to crash

Quest Link app: 78.0.0.988.310

OS: Windows 11 24H2 26100.4946

Firefox: seemingly any version now. V142, ESR, all the way back to 130.

 

After letting the Quest app update to the latest drivers, it is causing Firefox to crash anytime Firefox gets audio or video permissions.

Uninstalling the quest link app will make Firefox go back to normal. Re installing, the crashing problem comes back.

 

The quest link app does not need to be active.

Reproduction Steps:

Have Quest Link 78.0.0.988.310 and Firefox installed.

  1. Go to https://webcamtests.com/
  2. Click on "Test my Cam"

Alternatively

  1. Go to meet.google.com
  2. New meeting -> Start instant meeting
  3. Set the mic and camera permissions

 

In both cases, Firefox immediately crashes.

I have completely reformatted my computer and reinstalled everything, with the same problem.

 

As soon as the Quest Link app is uninstalled, the problem goes away.

    Can confirm this is STILL an issue, even after the update the other day. Please tell me they're aware of and working on this. I hate having to uninstall and reinstall the app constantly.
