A decent 3.0 add-on Rated 4 out of 5 stars
A comprehensive gestures tool for Firefox 3.0. Very similar to All-In-One Gestures for 2.0.
Compared to AIO, it sports a tighter interface. Gestures can now be defined either by motion or string from the same window. Commands are organized by class, allowing one to find and define more quickly. A script editor is also available to create high-order gestures.
Users of AIO will notice that the mappings are much more strict (e.g. "Open in New Tab" will no longer open blank tabs, and must be positioned on a link at gesture start). Also, "wildcard" gestures and multiple definitions are not available without delving into scripting. FG does not work in certain areas, such as the empty area around plug-in-only pages (QuickTime files, for instance).
