Whitelisting question with Firefox 29.0.1

Edit Subject

I have a question about unblocking individual Twitch pages. I want to unblock specific streamers that are partnered but not the whole site and it seems I am having a problem with doing so when it comes to whitelisting.

I will give you an example. One of the pages I want to unblock is http://www.twitch.tv/dizzydizaster and I have it set to whitelist the site. But what happens is that it doesn't just whitelist twitch.tv/dizzydizaster, it whitelists all of twitch.tv. Is there a way to just whitelist individual streamers or is the only option to whitelist the whole site?

Now, I could always unblock the individual page and then turn whitelisting off when I am done watching that streamer but it is easier just to be able to set it and forget it.
