One of the features that I love in Opera is its mouse gestures. The gestures that I use most is right click + right/left which enables me to go Back and Forward a web page. Ever since I migrate to Flock (Firefox based web browser) I somehow miss those features.

FireGestures is a great Firefox add-on that allows you to have the Opera-like mouse gestures in Firefox. It works outside of the box without the need to change any settings. If you are someone that love to tweak a software to its full potential, here are the features of FireGestures:

• Mouse Gestures (Move mouse with holding right-click)
• Wheel Gestures (Scroll wheel with holding right-click)
• Rocker Gestures (Left-click with holding right-click and vice versa)
• Keypress Gestures (Mouse gesture with holding Ctrl / Shift key)
• Tab Wheel Gestures (Scrolling wheel on the tab bar)
• 70 built-in commands which can be invoked by Mouse Gestures, 4 [Popup] type commands and 3 [Hybrid] type commands.

FireGestures is very customisable. You can download additional scripts to add more functionality to FireGestures.
