Personally, I am still experiencing issues. I'm not sure if they're FF related or NoScript or AdBlock. When I click on a users name to view their profile or send a PM, the page comes up 404. Very annoying to have to switch to Opera to do the things I want. Any suggestions would be very welcome.
As for PDFs I use Foxit; very fast and small footprint.
