FireFox hidden gestures
MacMagazine has released a tutorial on how to enable multi-touch gestures in Firefox 3.5. The gestures allow users to alternate tabs via twisting. By opening a new window or tab in FireFox and typing "about:config" into the address bar, users can gain access to a filter list; in some cases a warning message may pop-up when loading the filter list. Users then search for "browser.gesture" within the filter search bar, in order to get a full list of settings which consists of controls and gestures.
Within the settings users want to look for the options "browser.gesture.twist.left" and "browser.gesture.twist.right", which should be blank under the value portion. To enable the shortcut simply double-click on the first option listed above and a dialog will open, paste the command "Browser:PrevTab" inside it. Next click onto the second option and paste "Browser:NextTab" in it as well. If done properly the effects should be instant and allow users to now alternate tabs by twisting the multi-touch pad.
In order to remove the changes and return the settings to normal users just follow same the steps previously mentioned, except in this case, delete the pasted text and leave them blank again.
