I can confirm as well. it's not just firefox - I use the web developer
toolbar and have it open up source code in Gedit (which I assume then
becomes a separate process?). Gedit also crashes the system in the exact
same way. I resorted to gedit as View-Source was causing this issue
every time.

Hopefully this is the same bug, or at least similiar - I'm experiencing
similiar issues when going "view source" and then scrolling up or down
for a while. After about a page of scrolling the entire screen (not just
firefox in my case) gets corrupted for a second or two and then X11
restarts.
