For some stupid reason YouTube automatically plays videos on the watch page. This makes it basically unusable to me, because I want to browse YouTube and open many videos in tabs and then watch one tab after the other (or let it open in the browser session for some days before I close it again).
Up until now I could force YouTube to use the flash plugin (by sending an old Safari user agent string) and then I used the click-to-play functionallity of Chrome/Firefox to stop flash from automatically playing. But this does not work anymore, and neither did all the "disable YouTube autoplay" add-ons/extensions.
So I wrote this simple add-on that simply replaces all links to YouTube watch pages with a link to a "hop-page" that provides the real link (and a video thumbnail).
However, you will only get to the hop-page if you open the link in a new tab or window (via middle-click/context menu/D'n'D). Otherwise the normal watch page will still load so your normal YouTube browsing will not be disturbed (note: it will break YouTubes fancy dynamic page loading, which cause more troubles than good for me anyway, and revert to plain old page instead).

. There is also a Chrome and user script version of this add-on.
