Working great!

Simply doesn't work. Installed it and went to some sites I knew did autoplay video to test and they continued to do so, even after restarting Firefox.

per-URL config is wonderful (e.g.: disable-autoplay-everywhere-except-youtube)

EDIT: it stopped working completely for some reason

works fine!

Great... only issue is that when active, it then takes two or three clicks to _start_ videos, but it's well worth that cost.

Generally works perfect , but youtube comments don't appear with it ，please fix it ， thank you！

A bit annoying that it has to reload YouTube page to prevent autoplay. It also doesn't let to continue playing from the stop when I switch to YouTube from embedded video on other site. Would be nice to implement it or I will be grateful for an extention which has this functionality.

It works OK

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!
