A must have addon for Firefox.

FF58.0.2 x64
Doesn't work on certain pages. Options appear twice.
High cpu usage (25%) with this addon on certain pages (tested with only one tab and clean profile), even if video isn't playing.
Better set media.autoplay.enabled to false and change if needed with this bookmarked: about:config?filter=media.autoplay.enabled

Bardzo dobry dodatek,korzystałem z niego na chromie.Można dodać strony do wyjątków tak że nie ma najmniejszego problemu żeby oglądać swoje ulubione strony.

It works, but on Youtube it makes the comments section disappear. Under the video it is all blank, no comments.

Very good! Since the internal pref "media.autoplay.enabled" set to "false" does not work with Netflix as of Feb 9, 2018, THIS is the add-on to get control over autoplay.

XML files do not display properly when this extension is enabled

All this does is toggle the setting for autoplay which can be done manually. No way to disable per site. Useless.

very good

Works with some sites but not others. Problem with version 57+ Firefox?

Works very well!

Not perfect (had some glitches) but the only extension that I've found that actually offers a whitelist approach. I verified I can block on sites like CNN and can allow on sites like youtube & netflix. This should be built into browsers period and on by default. I can think of no good reason of ever wanting to allow this by default. So, good work.

Most of the time doesn't work.

Does not work in Netflix.

Woeks great. Thanks!

Haven't had a single problem with this add-on, honestly works even better than I expected. Very well done.

It's very simple. It does exactly what it says that it does. It works perfectly.

Sometimes works, sometime not.

Mimics the diasabled media.autoplay.enabled setting in about:config but provides a needed whitelist.

It's been working well. Thank you.

I can't disable totally for a single url

OK.
