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.
Can YouTube be started in pause mode?

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.
