[Bug 1586436] [NEW] mozilla (firefox/thunderbird) crashes randomly for seemingly no reason

[Leon Adato]

Public bug reported:

mozilla-based apps (firefox/thunderbird) crash randomly for seemingly no
reason.

Happens multiple times per day but not repeatable. Shortly after mozilla
apps crash, Chrome crashes as well.

Happens on primary desktop. Have replaced ALL hardware but the problem
"followed" me to the new system.

Happened on Kubuntu 15.10 and now Ubuntu 16.04

Happens (almost) regardless of which tabs I'm running in chrome/firefox.
