Can you paste the contents of your blacklist here? Or try temporarily replacing it with something simple, like var blackList = new Array('explicit', 'mature'); and seeing if it works? (I ran that on the page you linked, and it worked for me in Firefox 32.0.3 on Mac OS X 10.9.5.)
If it still doesn't work, are you using any other scripts or extensions in your browser? You could try disabling them to see if there's a conflict.

I'm sorry it's not working! I wish I knew why.
