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

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!

works fine, thank you!

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

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

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!

Works well for me so far. Thanks!

This add-on is broken with the new layout but works fine with the old layout.

So the workaround is to add another add-on, https://addons.vaultpit.io/en-US/firefox/addon/youtube-design-preserver/ with which we can change the default youtube layout & now everything works fine.

This add-on does exactly what it says it does, nothing more, nothing less. Youtube would always turn the autoplay next video feature back on whenever I would go to another video, which was quite annoying. I never want the autoplay slider on, and, with this add-on, I don't have to worry about it any more. Also, playlists still automatically play the video, in case you were wondering.

My thanks to the developer! This add-on definitely improves my Youtube experience.

Only add-on that worked for me!

Cool i like it alot

It works well.

It is working pretty well as of now. I really hope the developer can keep up with the updates since youtube is frequently changing their module rendering this add-on useless after about a week or so. I really wish there could be a way to PERMANENTLY down right disable the incessant nuisance that "upnext autoplay" is.
