Is there a URL parameter for youtube.com that makes it possible to open a video and not have it start playing automatically?

There is a parameter for the embedded player (autoplay=0), but this does not seem to work with the full site.

The TubeStop extension for Firefox prevents autoplaying YouTube movies whenever they appear (within Firefox).

The extension developer also provides a version for Chrome, which I haven't checked.

  • Hm, yeah. But nothing that would work everywhere. Too bad. Anyway, that's an answer, too.

  • For Chrome, I used to use the Stop Autoplay for Youtube extension. Haven't used it in a little while, but it always worked fine for me. Commented Oct 19, 2011 at 13:58

    TubeStop was discontinued on December 25, 2012 and is no longer supported, for both Firefox and Chrome.

try smartvideo for youtube. once installed, in the configuration settings you'd have to tick the box 'start playing when buffered' first before you can check "don't play; only notify when video has buffered."

works for embedded videos as well.
