Public bug reported:

Ubuntu: 19.10
Firefox: 74.0+build3-0ubuntu0.19.10.1

Since 2020.03.31 tabs in Firefox started to crash regularly on some websites (mainly Vbulletin and phpBB forums).
This happens also in --safe-mode.

stderr output (just this one line):

[GFX1-]: DrawTargetCairo::Snapshot with bad surface 0x7efdd6d99b00,
context 0x7efdd5cba000, status 0

When trying to reload tabs they keep crashing, but after like 10-20
retries they display properly and continue to work fine.
