I was cleaning out my macbook's hard drive this morning, and I guess I deleted some files that Firefox needs to run on accident. I didn't notice it till I tried to go to youtube and the page wouldn't load. Safari and Chrome are still correctly loading youtube so I know it isn't a problem with my internet. It seems to load most websites correctly, macrumors is obviously loading. I cleared out my trash bin when I was done so I don't have any of the files that could possibly be the solution to this. I removed firefox.app from my hard drive, cleared my trash bin again, and reinstalled but this still didn't solve it either. I've tried restarting my macbook, restarting Firefox, updating Firefox, opening and closing the application but nothing has worked for me so far. I'm attaching a screen shot of what happens when I try to go to http://www.youtube.com/. Any help is appreciated.
