Found in

  • 116.0b1

Affected versions

  • 116.0b1
  • 117.0a1 (2023-07-05)

Tested platforms

  • Affected platforms: Windows 11x64
  • Unaffected platforms: Windows10x64, macOS 12, Ubuntu 22

Steps to reproduce

  1. Open Firefox with --migration command.

Expected result

  • The migration wizard is displayed almost instantly.

Actual result

  • The migration wizard options are displayed only after about ~7 seconds.

Regression range

  • This started with Firefox 116.0a1 (2023-06-10) after bug 1823537 was implemented. I cannot see the issue with the old migration window.

Additional notes

  • Attached a screen recording.
  • Note that this happens only on my Windows 11 desktop station. We could not reproduce the issue on another laptop with Windows 11 and on Windows 10x64, macOS 12, or Ubuntu 22. So this may have something to do with my importing profiles.

:mconley, since you are the author of the regressor, bug 1823537, could you take a look?

Hi atrif,

Could you please help us gather a profile for this? That might help illustrate where the problem is.

Gathering a profile in this case is a bit tricky - you'll need to set some environment variables:

MOZ_PROFILER_STARTUP=1
MOZ_PROFILER_SHUTDOWN="C:\Some\path\for\the\profile.json"

The path provided to MOZ_PROFILER_SHUTDOWN is where the profile file will be written to once the browser fully shuts down.

If you've not set an environment variable on Windows 11 before, there are instructions here.

Once you run through the STR, please close the main browser window to write the profile file. Can you then either attach the generated JSON file here, or use https://profiler.firefox.com/ to view it, upload it, and post the permalink here?

Both profiles are from the same machine. I hope this helps!

Thanks, atrif! Can you tell me how many Firefox profiles you have on this machine?

Thanks, atrif! Can you tell me how many Firefox profiles you have on this machine?

Hello Mike! It seems that there were over 200 xD. I did a cleanup and the migration window opens almost instantly now. Thank you!
