I can't see the try results anymore - did bug 926605 change things here so that this orange is gone?

No it did not.

I believe the problem on Linux is related to async delivery of popup/focus events: when gecko things a popup (either the context menu or the notification panel) has opened, there are still pending focus events from X: this means that the various panels are cancelling eachother at random times during the test leading to the various failures with either the context menu or the notification not being open at the time the test expects.

Whoops. This is still a problem, we're just papering it over by marking the Linux version as random.

Resolving as wont fix, plugin support deprecated in Firefox 85.
