You must restart Firefox after installing this.
Then it will stop the autoplay on Youtube, as it says.
Thank you very much :)

Work like a charm!

It would be nice to still be able to turn it back on when I feel to.

Thank You So Much Dear "James Fray" , For This Brilliant addon , But this addon ,sometimes Doesnt Work , and should refresh the page , to work , Why????

The best add-on ever for youtube. They can't solve this problem with forgetting autoplay setting, but James did solved it. Thanks a lot!

Today, it decided to open its addons entry in a new tab without any interaction from me, costing me a bunch of work as I was typing on a form while looking at a piece of paper. It did it again on my laptop... again, without warning or input. That earns an immediate uninstall. Never *ever* interrupt the user like that.

Didnt work for me. FF60.4 esr, portable, 64-bit

Not working.

I wish Google would make YouTube more user-friendly but it is designed in a way to keep you in front of the screen as long as possible. It has become a bit less annoying thanks to this add-on. However, if used in combination with other YouTube enhancing add-ons it can create problems. Playlists keep auto playing videos, although I turned that off everywhere.
Basically, I cannot get YouTube the way I want and have to compromise..

As mentioned before, it works perfectly in one tab, but if you open a link from this tab to a new one it doesn't.

Doesn't work. Tried another addon and that one worked.

works fine, thank you!

It works as described. Thank you very much for developing such effective tools for YouTube.! :-)

It's not working if you opening video in new tab. :/

Thank you. Thank you. it stops the auto-next while other add-ons do not

Same as previous reviewer. Only works in the current tab. If I open a vid in a new tab it doesn't work.

But still it's better than nothing. Autoplay just loves turning itself back on constantly.

Works when clicking on a link directly but doesn't when opening a youtube video in a new tab. What's odd is it used to. I recently had to reinstall windows. Somethings changed, I don't know where... possibly at youtube because this addon used to work on videos opened in new tab. Note: None of the 'stop auto play addons' (if that's what they are?) work on videos opened in a new tab anymore so possibly youtubes changed something.

Didn't work for me. I set youtube to turn off auto play, but if I open a new youtube tab, it's right back on again

Dude...I finally switched from Firefox ESR version which kept all of my old reliable add-ons working (Flashstopper, Classic Theme Restorer etc.)..I STILL really miss the addon/search bars that CTR gave me & ability to use text for the icons among many things but the Youtube autoplay in this new version was killin me..This new Chromed up version of FF still annoys me but I tried Chrome and hated it even worse but ESR release was slowing down awful...tried a bunch of about:config hacks and some other addons here but only yours works for killin YT Autoplay..I am adding some money to my Paypal account to buy you a beer brother...god bless the developers

Works for me, thank you!
