Works as described Rated 5 out of 5 stars

FF 15.0.1, StopTube 0.1.0
Works for me. YouTube HTML5 videos do not load until click in the box where the video will be.
Nicely complements Flashblock.

Author: Have you considered releasing a Greasemonkey version of this?

This review is for a previous version of the add-on (0.1.0).
