Worked well in the past, but not anymore. There could be settings to set the number or time period for total replays to save NETWORK DATA because Youtube no longer allows wideos to be stored in the computers of viewers to protect videos from being downloaded or copied, but now it wastes a lot of network data because videos are being re-broadcasted each time.

Doesn't work

Doesn't work in Firefox Android.

It won't replay the video, and just skips to the next

Just sends YouTube videos into a tailspin (a shrunk video keeps wanting to expand) that won't play. This is just by having this installed (not even enabling the loop feature, which seems to be blank). Please preview things before you roll them out.

Will continue to use the old version (which works!) for this until all these new Web Extensions start working properly.
