Does anyone have continuous crashes with Firefox and Chromium?

As per title I'm having continuous crashes with Firefox and Chromium.
Chromium crashes very frequently (once per minute, even now when I was simply typing it crashed) , firefox less frequently, and I don't understand the reason.
Flash 11 was installed through the repositories

Hey,

If you manage to post what you have in your logs, specially /var/log/Xorg.0.log, /var/log/syslog and /var/log/dmesg it will be much easier for people to understand what may be happening there and propose a solution.

If you need help doing it, check my posts from yesterday. I posted a set of commands on how to get this log files, zip them and publish them here.

Regards,
Effenberg
