Switch tab in Firefox with swipe left/swipe right gestures I have a MacBook and I'm using Firefox. Using the editor on the about:config page, I wish to modify the options of browser.gesture.swipe.left (or right) such that it will switch to the tab to the left (right) instead of going to previous/forward pages.
What should I write in the string value for that?
Thanks
Previous tab: Browser:PrevTab
Next tab: Browser:NextTab
