Steps to reproduce:

https://old.reddit.com/r/openSUSE/comments/15jygg0/slow_firefox_startup/

Is it just me that's experiencing slow Firefox startups in OpenSUSE? I tied Ubuntu and it had fairly quick startups.

My old tumbleweed PC had a shit GPU setup, so I didn't mind the slow startups. But I now have a Ryzen 5 5600G desktop and I'm still getting slow startups.

I copied the old ~/.mozilla/ folder to my new PC, and it's been slow to startup as well.

I tried using the https://profiler.firefox.com/ and running with:

MOZ_PROFILER_STARTUP=1 MOZ_PROFILER_STARTUP_ENTRIES=20000000 firefox

• OpenSUSE Tumbleweed
• KDE Plasma Wayland
• btrfs

I tried:

• firefox --safe-mode
• Deleting/moving ~/.mozilla + ~/.cache/mozilla
• New User
• Plasma XOrg

All attempts took 20+ seconds to open Firefox.

Actual results:

and noticed it's spending 10+10+5 seconds stuck polling the lock files.

The lock file appears to be a symbolic link pointing to localhost:+18462 which I didn't even know links could do.

I also noticed a Telemetry.FailedProfileLocks.txt file with the number "9" inside it. Might be from my older PC install. It doesn't update each startup.

Expected results:

• Kubuntu 23.04 (startup was only 2 seconds) ext4
• Ubuntu 22.04 (startup was only 2 seconds) ext4

Both tested on same M.2 drive in different partitions.

The Bugbug bot thinks this bug should belong to the 'Core::Graphics: WebRender' component, and is moving the bug to that component. Please correct in case you think the bot is wrong.

I typed up the stack trace in the screenshots for reddit and figured I'd post it here too.

Could you upload the profile data ("Upload Local Profile" in the upper right) and post a link to that?

(Preferably from a new Firefox profile, to minimize both logs of unrelated events and disclosure of private information.)

Is your home directory a local disk or is it a network mount of some kind?
