My firefox has been really dragging a$$ lately. Every time it really hangs it was reading google analytical or something similar. After doing a bit of checking around, I downloaded a NO SCRIPT add-on from mozilla's website. I am simply amazed at how fast the thing runs again. If you are having similar problems, I highly suggest this add-on. Initially it did screw up a couple of of my standard pages (1 online banking site and the weather channel) but 2 simple clicks allows you to allow specific scripts to work on the pages you want.
