I'm locked out of my Quora account, at least via Firefox. I don't know how I logged out (it was unintentional) but when I enter my username and password at their login screen, the submit button is unresponsive. I contacted Quora, and they couldn't reproduce the problem using several browsers, including Internet Explorer and Firefox. I cleared two days' worth of history, and even reinstalled Firefox. No results. Along the way, I tried it in IE9, and it worked fine. (I don't use Google Chrome because it got to a point where it didn't play and get along well with my computer, never seemed to close completely, frequent BSOD upon opening . . .) One thing I noticed with IE: when you log in to Quora, when you enter your e-mail, your name and profile pic display while it waits for you enter your password and click submit. This doesn't happen in Firefox, either. Do I possibly have a Firefox add-on that's messing things up? Can it be fixed? I'd like to keep using Firefox, but I'm a bit of a Quora addict, and I hate Internet Explorer . . .
