Addon fails to block ad-videos on most famous streaming-site Twitch.tv, the ad-videos that run before the actual stream-content.

One of the VERY FEW addons that is really good and works well. Easy to block objectionable images on webpages so as to deny them ad revenue, like with sites that mistreat users. Only criticism I have is that when using an encrypted connection like with a vpn or tor, the settings do not stay and you have to reset the blocks. I'm guessing its because the ips and other stuff changes with tor so cannot make the blocks permanent. Great extension over all. Look for other add-ons by this author they will be good.
