Firefox has issues loading pages

I recently installed Ubuntu and have been enjoying it... except for Firefox. It has issues loading pages. Sometimes it will loop loading for ever, sometimes it still start to load the page and then give me an error about connection, sometimes it will load just fine. I notice this mostly on Southperry, Reddit, Youtube, and Facebook, but that might just be a result of using them more.

Not sure what to do or what to Google, any advice guys?

32-bit or 64-bit?

64 bit Ubuntu 11. Firefox 4 came with it.

Youtube and Facebook uses Adobe Flash, and the 64-bit version is worse than the 32-bit version. Might be because of that.

Otherwise, I don't know - sorry =|

I've heard that before.

I'm not noticing any issues with Chromium though, so it might just be firefox.

Edit: Just disabled Greasemonkey and everything seems fine....
