During the Firefox 3.5 beta, a few people stumbled upon a neat, unadvertised feature. By twisting their fingers on a Macbook’s multitouch pad, they were able to roll through their loaded tabs. But Firefox 3.5 (official) deactivated the trick. However it turns out you can actually reactivate it.
Luckily, as Crunchgear explains, the multitouch trick can be reactivated!
- Simply open a new tab (I’ll wait) —
- Put “about:config” in the address bar, no quotes. It’ll ask you if you’re sure. Yes, you are. You are okay.
- Ready? Okay, now type “twist” into the search box.
- Double-click on the twist right, and put “Browser:NextTab” into the box, without the quotes.
- Theeen, in twist left, put “Browser:PrevTab” without the quotes.
- You’re done! Now, I found the gesture (it applies immediately, try putting one finger down and rotating another around it) to be a bit slow to respond, so I changed that other setting, the threshold one, from its default (25) to 10. You can mess around and figure out what’s best for you.
You can read the very simple instructions over at their site, then realize that you can actually modify the settings to use gestures beyond the twist (like a three-finger swipe). But until we see incorporation of middle-finger-activated autotrolling, we’re holding our excitement at bay.

It‘s quite in here! Why not leave a response?
