[Sebastian Hengst [:aryx] (needinfo me if it's about an intermittent or backout)]

Based on the screenshots, no web content is loaded and the devtools also haven't loaded yet. Honza, could a person from devtools look into this? Else many flame graph/performance tests will need to be disabled, similar to the ones mentioned below.

Looks like this has been fixed by bug 1722136 (no failure since then)

Closing as dup
