Is there something wrong with Safari?

i have the newest version of Safari and lately it's been doing some very weird things. All of a sudden it stopped working with a lot of the sites I frequent. When I go to Pandora.com, it only loads the blue screen then stops. When I go to my netflix account and try to watch something online, it tells me I need to install their software, which I've already done, I even did it again just to make the message go away, to no avail. I am trying to get itunes to send my nike+ workouts to nikeplus.com, and it just never loads. I thought if I uninstalled then reinstalled it would help the problem, but nothing is working. Does anyone have any suggestions as to what I could try doing next? THanks!

Have you tried another browser ( ie. Firefox, Chrome, Opera, .... ) and what are the results ?

Yeah I've tried them all. I think I've just nailed it. For some reason "Allow plug in's" was unchecked in my Safari preferences. This has been causing me grief for weeks! LOL.
