I posted this on the Ubuntu forums. Just got one reply, from someone experiencing the same problem. I am hoping someone here can offer some advice:

Prior to the latest update (within last week) I was getting FF crashing on some web sites. My best guess is that the sites had lots of javascript.

Sure, what websites? Can you use chrome to get to these places?

Now, after the update, I am getting FF locking up my desktop. I need to do a soft reset to get going again. Very much no fun.

Can you access these places from another machine/os/browser?

CPU is Intel i5, 64 bit, 16 GB ram CPU temperature app shows good numbers. I run the Gnome shell. I use the machine as a LAMP and SAMBA server.

I have never had trouble like this before.

Suggestions and advise requested.
