You can check out 911 Tabs, they have their own tabs + they have links to other sites.
Though I don't suggest using chords/tabs for anything else but learning how to play the guitar. If you are already farmiliar with guitar chords, notes, riffs etc. it is very important to try to figure out how to play a particular song just by listening at it. If you find it hard, there are some softwares that slow down the tempo of the song so you can hear it better.
Of course, if you don't want to master the guitar and just want to learn a couple of songs so you can be the cool one in the crowd, you don't need that
