I've been using this adblocker for ages and it's been fantastic, however recently it's been completely breaking sites. At first, I thought this was a change made by google, as youtube and google calendar were the first things I noticed, however it's also affected unrelated sites like trello, pillowfort, and tumblr. I've had to disable it on about half the websites I use, and rely on other adblockers when I didn't before.
