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.

I HAD TO DISABLE THIS BECAUSE EVERY TIME THE BROWSER STARTED AN OPTIONS PAGE WOULD LOAD. HOW MANY TIMES DO YOU NEED TO FIDDLE WITH THIS THAT IT NEEDS TO ASK EVERY TIME? MUST BE A WAY TO ASK FOR MONEY WHICH IS AN ANNOYANCE AND THIS EXTENSION DOES SO LITTLE IT'S EASIER TO ACTIVATE MOMENTARILY THAN TO HAVE IT BUGGING YOU ALL THE TIME.

THANKS FOR YOUR QUICK RESPONSE.
I HAVE FF SET TO AUTO UPDATE SO I HAVE NO REASON TO SUSPECT A BUG. I FOUND DISABLING THE ADD-ON STOPPED THE POP UP.

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...

it does not work

Fireox ESR 52.4.0

Doesn't work! Furthermore it should actually do what it says and stop media from automatically streaming or playing media unless the user clicks a play button not just stop or in this case hide the play next video in YouTube. Fail.

There was an addon conflict that for a while made this add-on only hide the toggle, leaving you only the ILLUSION that it's disabled. While searching for the conflicting add-on itself hasn't yet shown results, the problem went away after an update to Youtube High Definition by Baris Derin.

This extension does what I expect, but the fact that the extension shows notifications on every update is annoying and I want to be able to disable that.

“on every update” = every time an update for this extension is released and on first install (at least, that’s what I got from `data/main.js`).

It worked until the new Youtube layout.
Edit: Now it works, thanks for the update!

This worked fine until the most recent update of Firefox - 50.0.3 (64bit). Now it has stopped working.
