Recently I'm getting screen freezes, followed by "not responsive" messages. It appears to happen when when some of the sidebar ads change. It seems to happen more with Firefox so badly it's impossible to post...I'm posting this on Chrome.

Any suggestions besides the obvious "just use Chrome"?

Alex I am using firefox and I am not suffering any of these issues, I would suggest looking for something that has got onto your system.

Thanks but I got it working.

The problems seems to have been with the Firefox plug-ins. Flash auto updated last week so I figured that was probably the culprit, especially since Chrome seemed to work. I reset flash to factory and then updated.

I've had Armorama and Photobucket both running for the past hour without any crashes so I'm feeling pretty good about it.

Glad it is sorted.
