I enjoyed Grooveshark.com until a couple of months ago when it stopped working on my iMac.
Now when I go to Grooveshark.com, the page will begin to load then instantly go to a completely blank white page. Can't do anything. It works fine if I use it on Firefox. As far as I know, I'm not having issues with any other sites.
A little suprised to find the extension that was the problem was...Defacer 1.0.2. It is supposed to.....Remove "like this" and other facebook-buttons from websites" Instead it stops Grooveshark from working at all.
