I have been using this extension for the longest time. It never broke until the most recent YouTube update. It's not really the developer issues as far as I can tell not to mention this extenison is one of the best if not the best YouTube extension one can install.

Now with the latest fix, the Cinema Mode problem has been resolved.

This extension is worthy of a min. of 4.7/5 Star overall rating after a few years of use. It's only fair to the developer of this fantastic extension. I almost never give a rating higher than 4 Star unless it really worth the high star rating. I also seldom write reviews. This one certainly deserves the accolade. Hope this carries on into the future.

I highly doubt you can find a better one out there. Unfortunately, there are some who prefers to nitpick on just about everything. That's unavoidable.
