firefox and thunderbird randomly segfault

[David Demelier]

Hello dear,

After an update, firefox and thunderbird randomly segfault at any time.
It a bit annoying and I can't find the cause :

pid 5586 (firefox), uid 1001: exited on signal 11 (core dumped)
pid 5609 (firefox), uid 1001: exited on signal 11 (core dumped)
pid 5611 (thunderbird), uid 1001: exited on signal 11 (core dumped)

Do you have the same issues ?

firefox-27.0_1,1
thunderbird-24.3.0_1

Regards
