This extension seems to create a memory leak in Firefox, and unfortunately slows down YT a lot in its process. Too bad, seemed really good on paper.

Nice Idea an worked good for a while. But since a week or so it significantly slows firefox and youtube making watching stuff basicly impossible. Pls Fix

Не сохраняются выбираемые пункты настройки. Нажимаю вкл - само переключается обратно на выкл. Ни один бегунок не сохраняет положение.

Update:Slows down youtube page loading! Fine youtube addon apart from the below mentioned issues. Rest of the ui blocking thing and others are working fine and are absolutely essential for using youtube!
Original:Comment blocking is not working. Also extension is currently not intuitive especially if you want to use content filtering. Content filtering or the extension itself should open in a new browser tab for options for ease of access and use.
