Firefox (Vista OS, up-to-date on all patches) works fine for several minutes, and then hangs up on reload (manual or automatic) or click. During the hang, all display functions (like mouseover) work fine, the prompt indicates busy, and the status (lower left) is "stopped". I can exit with no error, but can't restart unless I kill the Firefox process (which hangs around despite the exit).
I have tried running in safe mode, with administrator privs., and with a new profile.
The New York Times page seems especially problematic, but it isn't the only place I've had trouble.
The trouble began with 188.8.131.52 about a week ago. I hoped that upgrading to 3 would help, but no luck.
Thanks for the help!
