Firefox 3.5 had experimental support for multi-touch gestures through out beta, but in the final version the support has been hidden by default. The gestures were compatible with Macbooks and Macbook Pros that have multi-touch enabled track-pads. These multi-touch gestures for tab switching can be enabled by the following instructions:
- Type in about:config in the address bar and press enter.
- Press the “I’ll be careful, I promise” button to go to the next screen.
- Type “twist” in the search box.
- Double-click “browser.gesture.twist.right” and put “Browser:NextTab” into the box, without quotes.
- Similar, double-click “browser.gesture.twist.left” and put “Browser:PrevTab” into the box, without quotes.
- Now the gestures should work. Try doing a twist motion on your track pad. If the gesture is slow to respond, change the “browser.gesture.twist.threshold” value from 25 to 10 or less, whatever suits you best.
This should make tab switching easier for you if you’ve got a compatible Macbook. No word on whether this works with multi-touch displays on Windows, do let us know if it does.
