  • Das war reine Zeitvershwendung, Autoplay ist bei mir weiterhin Aktiv. Addone wieder entfernt :-(
  • "NO ZAKU"
  • no work
  • Urgently in need for such an add-on. Good that someone tried to develop one. What a pity that it is not working with html5. The developer (Nikola Kovacs) put much work into [https://addons.mozilla.org/de/firefox/files/browse/169666/], would like to contact him.
  • Seems to not work; FF version 20.0 (beta), 64 bit. Win 8.1, I7 Dell XPS-15 notebook. All extensions, addons, etc are updated to latest available.
  • Does not stop Youtube autoplay at all so 1 star.
  • It would be helpful if we could use this addon again. Hope you have time and interest to update. Thanks.
  • Love this addon.. but incompatible with latest FF.
  • Please update it, as flashblock blocks flash presentations & is based on a whitelist.
  • Totally finished with the endless updates of Firefox now on Vsn 26.. ye gods..

    So.. it updates itself automatically.. and deletes your Add ons.. so suddenly my addons need replacing or wont work with this version.
    And the endless hassles with Flash crashing.. ok time to say GOODBYE FOREVER..
    Thank god for Opera Browser.. forget Chrome.. what a heap of junk THAT is..


  • too bad it is not updating anymore.
    use greasemonkey with script Youtube Stopper" instead ;)
  • This does everything it says it will do...on older browser versions that is.. I use Pale Moon and rolled back to version 20.3. This now works again perfectly. I've disabled updates to my browser to avoid the Firefox update circus which doesn't do the users any favours whatsoever. ( Especially the addon developers !! ) . So if you want this great addon back until the developer updates it just go back to a previous version of your browser. Personally I'll keep my eye out for the time that Mozilla stop churning out these so called ' Major Releases' , stop trying to compete with Chrome directly and return to their senses.
  • It's because of add-ons like this.

    You get a really annoying problem with Firefox, for example it crashes, and when you restart it, every Youtube video then starts playing simultaneously with every other!

    What a racket! How fast can you find every tab that has a Youtube video on it and turn the things off?

    So then you think: "Well, someone else must've had this problem and come up with a fix". So you search the add-ons and "Yippeeeee! There's a fix for it".

    Except, the add-n doesn't work for the latest version of Firefox!!

    Why can't Firefox get stable, stay stable and just take a rest for a change? Every week there's a new version and half my extensions have to be updated. OK, slight exaggeration.

    Hey, Mozilla! It's not a race to get to version 583, y'know. Nobody cares what number it is, and the bigger it is does NOT mean it's better. In fact, you just annoy people with all these updates.

    I was quite happy when it was version 3.6. But instead of 3.7 it jumped to 4. Then 5,6,7,8,9...

    will you slow up? Give the poor add-on writers a chance to catch up?

    I have a feeling that if you - Mozilla - haven't got the basic core of Firefox sorted out by now, then you never will.

    And remember this, Mozilla, Firefox was written for the add-ons. End of. If people don't use add-ons then why are they running Firefox. They may as well use Chrome.

    End of rant.

    PS. Dear Nikola Kovacs, if you can't find the time to update this add-on, can you please let someone else do it?

  • This doesn't work with Firefox 23. please update it.
  • This add-on doesn't appear to work.
  • doesn;t work
  • not working with FF 21.0
  • simply doesn't work.
  • Please update to FF 20.
  • don't work (
  • Yep. It USED to work but "USED" is the operative word, here. What it USED to do does not do a thing to fix the problem, today, so apparently some want to perpetuate a lie concerning a tool that USED to work but does not now, work, and has not worked for a few months, now.
  • I will give the 5 stars for all the time I used it and it worked perfect. Suddendly it stops working. Hope the developer finds the proper time to fix it.
  • do nothing.
  • this extension used to be great. 5 stars to compensate for those who don't read the notes
    SmartVideo For YouTube is also not doing the job since the update to 19.0.2.
  • Doesn’t actually do anything.
