Would like to see two features: Hiding applies to specific phrases in URLs in addition to on sites themselves, words are replaced with something or blacked out instead of just removed as it can be confusing when not actually streaming.

Revising my review. I had an issue with Twitch not displaying, which then turned into multiple websites breaking. After restarting firefox and reapplying my whitelist, the issue seems to be resolved. Protects my info well!

And after another week with it, it's unfortunately not stable enough right now to continue using. Even on supported sites, I'm getting slowdowns/freezes/crashes. Still, it seems to be the only thing providing this functionality, so if you need it, you need it.
