Here are some examples of Firefox on Windows XP, OS X, and Ubuntu.

Um, I don't really use any of them that often, so there's pretty much a guarantee that they're all on the default settings and I did make sure to update all of them (though I'm not 100% sure about Ubuntu's).

Ubuntu
OS X
Windows XP

And just for kicks:
IE (who knows what version) Windows XP
Safari OS X

As for how I can stand using Safari? *shrug* I pretty much just need it to browse the internet and it does that just fine. I've heard people complain about it before but I've never really seen any reason to switch. Well, except that there may be a memory leak issue.

Also of note: I don't like Rilo Kiley.
