Fedora 30 (Workstation Edition) - looks as very outdated setup.

Hi! I'm hitting this crash as well (https://crash-stats.mozilla.org/report/index/62a12a80-9789-4a19-bebe-bbcfc0220315), when trying to open Firefox Nightly 100.0a1 and Beta 99.0b3, on a wayland session. I'll leave my STR in the bug.

Steps to reproduce

1. Open a terminal in Ubuntu.
2. Ran the following two variables in terminal. Press enter after pasting each variable.

• MOZ_ENABLE_WAYLAND=1

• export MOZ_ENABLE_WAYLAND=1

3. Launch Firefox from the same terminal opened in step 1.

Let me know if I should file a separate bug for this.

Weirdly enough, I keep getting this failure on try and I have no idea why: https://treeherder.mozilla.org/jobs?repo=try&selectedTaskRun=e2UKLsxBSNGenqlq7NoDdQ.0

Since the crash volume is low (less than 5 per week), the severity is downgraded to S3. Feel free to change it back if you think the bug is still critical.

Hello,
I tried to reproduce the crash using the STR from comment 2 without success. Could you please verify the fix on Firefox Beta?

I reported this based on crash stats, so I haven't tried to reproduce this myself. I don't actually have access to a Linux machine at the moment.
