Can you open "about:crashes" in a new tab, and check whether there are
reports corresponding to the timestamps when you experienced the
problem? Have they been submitted?
Did the problem start happening just after installing a firefox update?
(i.e. were you using an older version before yesterday?)

Title:
Tabs in Firefox 74.0 crash on some websites: [GFX1-]:
DrawTargetCairo::Snapshot with bad surface
Status in firefox package in Ubuntu:
Incomplete
Bug description:
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.
