[Bug 1717370] [NEW] flash plugin crashes (or deezer web client)

[Damián Arias]

*** This bug is a security vulnerability ***

Private security bug reported:

First sorry for my bad english. The next problem happens in tabs of
firefox 55.0.2 64bits ubuntu studio 16.04.3 lts. and shockwave
27.0.0.130:

The problem is that if I have deezer open, I can not see videos in
instagram and youtube. I have to close the deezer tab for
instagram/youtube works without problems. My tests: put flash plugin not
on always (only activate with deezer), desactivated all my extensions,
close and reopen browser, reboot system, eliminate history
browser.....and nothing works.

Thanks for the help-
