Weird message, crashes Safari

[blooz]

There is one site I go to (it's a daily comic) which i have been visiting for a couple years now. Today when i clicked on it I got this message.


I have social fixer on facebook, but I never look at facebook on safari, only on firefox. I disabled the social fixer but this message still pops up. I have to force quit Safari and restart to be able to use it.
has that site been hacked or corrupted (it's the only one so far—and i am in Safari as i type this.)

PS
There is no problem in Firefox.
The site is:
http://www.dumbingofage.com/

it seems to be because i disabled javascript.
