[CentOS] firefox is incredibly unstable

does anyone else have major probs with Firefox as installed on CentOS5?

ever since the RPM for FF3 came out it has been crashing daily. Usually when I 
use Save As... or Browse... or anything else that brings up the Gnome file 
picker. After the crash I re-start then the file picker works for a while. 

Sometimes it just takes scrolling or click+drag an image or some other random 
action. BANG your'e dead. Very frustrating.

Now today it is just crashing randomly, I am not even touching it. Maybe one 
of my plugins, I know. I guess I will run it with debugger/strace. but does 
anyone else see this?

$ rpm -qa firefox
firefox-3.0.2-3.el5.centos
$ cat /etc/redhat-release
CentOS release 5.2 (Final)
$ rpm -qa kdebase
kdebase-3.5.4-18.el5.centos
