TTV LOL removes Livestream ads from Twitch without compromise in video quality or the plagued "purple screen of death"

Purple Adblock is an adblocker for Twitch which is available on Firefox and Chrome. It works by getting the stream from a proxy server, which gives the extension the original stream that doesn't include ads.

Twitch Adblock blocks ads on Twitch by switching to an ad-free version of the stream at 480p during the ad-time and automatically switches back to the original video quality after the ad-time is over.
