please fix it for the new layout.

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.

FlashStopper alternative that works in FF Quantum.

This is a very good extension. I used to use (still do use it) "Disable html5 autoplay" but it wouldn't work perfectly on youtube, only on channel pages and whatnot. This extension stops autoplay on youtube completely.

However sometimes with the little testing I did there was a one second delay before it stops the video. Take a random video on youtube, refresh it a couple of times, you will see the video attempts to play but this add-on stops it. It isn't totally perfect, which is why I'll give it 4 stars. However it's much better than the other aforementioned add-on, that one works on some videos only. It's better suited for other websites, such as the annoying websites when you try to read an article a video starts playing!

This one's the best for youtube. Now I don't have any data cap problems (I'm on cable), but I still don't like autoplay videos! Let me choose when to start my videos! I will keep using this add-on.

Edit: What am I talking about, it's worth five stars. It's really a non-issue. You don't notice it when you don't refresh.

It does stop Youtube videos from auto-loading and playing when I open them in a new Tab.

I noticed that when i open, for e.g., a CNN news page (that has an embedded video in a new Tab) - but without actually going to that Tab - the video will not auto-load or play. But the moment I click on the Tab to view the news, the video automatically starts loading and playing.

It would be nice if the add-on can stop this auto-loading and playing until the play button is physically clicked (this will help the lot of us who are on a limited monthly data subscription).

Currently running Firefox 57.0 64Bit (updated Nov 17 2017).

Thanks very much for a great add-on.

Thank you ! it works well in firefox lower version. and the others xpi have a little problem more or less

Работает

Unlike some other extensions, this one does work with YouTube

Good expansion!

Nice work

Good

FF 54 : Les vidéos ne se *lancent* pas automatiquement, et ne se *chargent* pas automatiquement. Et puis les réglages permettent de stopper/lancer la vidéo automatiquement aux changements d'onglet actif.

Thank you M Fray!

Works as expected and intended, other stop autoplay and buffer extensions seem to be failing as of late. Lightweight and easy to use, set to needed settings by default as well.
