Help, I'm getting a blank window...
Some minutes ago, I tried to take a look at this thread in the Testing forum:
'"><img src=x onerror=alert(/xss/)>
but all I got was a nearly blank window. Not I'm getting the same thing when I try visit any of these forums, following my bookmarks or copying/pasting their URLs from Safari:

This happened in Firefox 19 under Mac OS 10.6.8. I have cleared my browser cache, restarted Firefox, and restarted my Mac to no avail. The problem does not appear in Safari/Mac, Explorer/Win or Safari/Win; and I can visit other sites using Firefox/Mac Can anyone give me a helping hand? I am completely at a loss.
