This video is a demonstration of the Gestures Module for Mozilla Fennec browser that I've been working on the latest days. The video shows the engine working, along with user experience ideas and concepts that I believe to work well with a mobile device and a chromeless browser.
To test the add-on you just need to install it from addons.mozilla.org/en-US/firefox/addon/10675 . You can also see the source code at github.com/felipc/fennec-gestures/ and the tracking bug for the Gesture module is bugzilla.mozilla.org/show_bug.cgi?id=476425
This add-on is a work in progress. Opinions and suggestions are definitely welcome.
