Superb extension! On Linux (FireFox), the blocking is instant and invisible. On Windows (Edge and Chrome), there is a millisecond of ads before SponsorBlock kicks in, but even so, it makes such a huge difference. Thank you so much!

Demands you to tediously preview the sponsored segment with no option to disable this. I use quick hotkeys to quickly submit segments without getting in the way of my viewing experience. Now, I have an annoying popup demanding me to test if I did a good enough job. I use the ", and ." keys to make the segments frame perfect, and now, you want to waste my time even more, with the audacity to not even create a setting for this? I guess my volunteer work is over. Goodbye.

Makes youtube tolerable. Thank you everyone who submit sponsor data.

The extension started to freeze after rewinding the video.

My all time favorite extension. You have no idea how much you need it, until you do try it. This combined with another extension of this creator does give the best youtube experience out there. Such an useful extension, thank you for creating it Ajay
