Little FYI...if you're getting into an SSI and it wants you to install something, and then says that you have to restart firefox...if you have your settings so that your cookies etc will be erased when you close firefox...you're not going to be able to continue with that survey. Which is a bummer, b/c it felt like it was going to be interesting! (so much so that I allowed the install, which I never EVER do!)
