It's really simple and it works.

What a great idea! Thanks very much for this. The only thing is, whenever I see its logo, I think it's a switch I must click to turn it on—but that's just me, not paying attention. 🙄

For the last week I've been battling autoplay. I go into settings and turn it off but the next video and all after it in my "subscriptions" kicks back into autoplay. Over and over I turn it off and it just starts again. Installed this add-on and the autoplay slider in the video was gone and autoplay was no longer a problem. Now I have to find an add-on to defeat the CC coming on automatically and the format of the page switching to "grid" from my preferred "list." Love/Hate YouTube...

It works great stopping Bing autoplay. Thank you!

No longer works since the last youtube changes.
Was a life saving before.
EDIT: Fixed. Thank you!

works well.
firefox version : 78.0.2-1.fc32

It does the job.

Nice. Seems to work fine. The youtube setting is removed. The recommended videos appear but the timer doesn't, as expected.

Just what I was looking for, and works beautifully. Contribution sent.

Does what it says! I wish I had money to send to the developers, as we need more like them!

I've been looking for something like this since 'Stop AutoPlay Next for YouTube 0.1.7' stopped working in July 2018. Nice work.

Simply works!

Excellent add-on. Thank you.
Suggestion: It would be great to have an option for disabling annotations as well.

Finally a good extension which does not require "access-your-data-for-all-websites", because:

https://support.mozilla.org/en-US/kb/permission-request-messages-firefox-extensions#w_access-your-data-for-all-websites

The extension can read the content of any web page you visit as well as data you enter into those web pages, such as usernames and passwords.

FABULOUS!!! Works with Firefox 57 like a charm! Finally something that works! Thank you, thank you, thank you!!!

Using with Firefox ESR 52.5.0 (64-bit), works perfectly...
