Doesn't work in the new interface Youtube

Doesn't work ... Rated 1 out of 5 stars

Even the "fixed" 1.0.3. does absolutely nothing.

Flashblock for example works fine with flash content, but disables the ability to maximise the player for example.

Suckage Rated 1 out of 5 stars

Non funziona per niente, schifo totale.
It doesn't work at all, totally sucking.

Good one Rated 5 out of 5 stars

Doesnt require restart. Does not try to sell you anything. Good autoplay stopper.

1.0.3: Still Not There Yet Rated 4 out of 5 stars

Unfortunately 1.0.3 sporadically fails. I intentionally avoided 'rarely' because it seems to miss about 30% of the videos.

Updates come out and these developers are expected to adapt instantly. I have a life outside of Firefox, I imagine they do too.

Thank you for all your hard work. I'm still happy using this app.

come BAA-AACK! Rated 5 out of 5 stars

eagerly awaiting that update - the ability to so easily keep all that yammering at bay while browsing videos is sorely missed.

Decent Idea Rated 1 out of 5 stars

It's a good idea, but it doesn't work anymore.

Rated 4 out of 5 stars

1.0.3 isn't working anymore even after *leaving trial* of HTML5. I read about the intended fix to circumvent the Youtube upgrade. Having said that, it's a great tool. Saves lot of bandwidth.

nice, finally you fix it GJ

Update works just fine.

Thank you for reacting so quickly!

edit (30-September-2012): I think it’s not working again (FF v. 15.0.1; add-on v. 1.0.3, YT HTML5 is off).

Update is out, but it's not yet reviewed, check the description.

It was working fine, until this morning Rated 1 out of 5 stars

I don't know what happened, but all of a sudden it doesn't work at all anymore. I had 5 videos up & they all started playing at the same time! I hope you fix this soon or i'm gonna have to uninstall, it's really annoying!~

Fixed

Go to https://addons.mozilla.org/firefox/addon/stop-youtube-autoplay/versions/ and install version 1.0.3.

Works about half the time Rated 4 out of 5 stars

When it works it's great. But it's very inconsistent. For example, these videos still autoplay with the extension installed and enabled:

http://www.youtube.com/watch?feature=player_embedded&v=GCXHPKhRCVg
http://www.youtube.com/watch?v=SXam2uyd3-o&feature=player_embedded

What makes these videos different from the ones that don't autoplay, I have no idea. This would be a five-star extension if it worked 100% of the time. Or even 90% of the time.

UPDATE: Yes, sure enough I am in the HTML5 trial. Well, I still can't go to five stars given that not all YouTube videos are stopped by the extension. However, I will bump it up to four stars given the developer's quick answer and awareness of the issue. Hopefully it can be resolved, and if and when it is, I will happily bump this up to five stars.

Html5?

Are you in the html5 trial by any chance? If you right click the video, the last menu item will be "About HTML5", which is the case for both of the videos.
It seems Youtube changed something with html5 videos and broke the add-on.

Great Great Great Rated 5 out of 5 stars

Rated 5 out of 5 stars

Amazing addon, now I can:

1. Open a video in a new tab for later viewing, like I do with all other webpages (don't know why Youtube thinks they are so special that you want to see the videos immediately).

2. Open multiple videos without the hassle of switching to each tab and pausing them.

This should be the default Youtube behaviour.

Good job!
