[Bug 1644192] [NEW] "firefox 50" crashes frequently

[G.M.]

Public bug reported:

Hi,

Just dist-upgraded my 16.10 this morning. FF50 came with the upgrade.

In less than 1 hour, it's the fourth time it crashes!!!!!

The last crash, I had 4 tabs opened:
- a google sheet
- http://jango.com with a song playing
- http://mindmatcher.org
- https://framanews.org/ttrss2/index.php

I also had a second window opened with a single tab:
- https://solutions.researchgate.net

I was trying to copy (C-c+C-v) a cell to another when FF crashed and
abruptly closed all the windows.

I can't find any log with more info...
[EDIT: I just found that line in my dmesg:]
[ 6364.448376] Chrome_ChildThr[23754]: segfault at 0 ip 000055d952cdaae9 sp 00007f2d2ddfe370 error 6 in plugin-container (deleted)[55d952cd2000+3e000]

PS: It's quite annoying, when trying to report a bug about FF50, using
the specific expression "firefox 50", to get a proposition of *all* the
previous bugs for *all* the *previous* versions of FF!
