I'm actually using SuperOS which is an enhanced version of Ubuntu 9.10. My Firefox version is 3.5.7.
The problem - when I shut down FF , most of the time it keeps running somehow - CPU usage shows 96 - 100%. Sometimes it will shut all the way down, sometimes about 30 seconds, but most of the time I finally have to open the system monitor and end the process. To back up a bit, I was having this problem before, and burned a new CD, Installed it using the entire HHD space to get a fresh start - to no avail.
The reason I think it is Ubuntu specific is that I have the same FF version on my Mint8 machine and there are no problems.
EDIT - I knew I was forgetting something - I do close out all tabs before shutting FF down.
