2-fingered swipe used to go backward or forward in Mac Snow Leopard, but it doesn't work now that I moved to Lion.
System preferences -> Trackpad -> More gestures
Make sure "Swipe between pages" is checked, and you can change the gesture in the drop down box to what you want it to be.
Thanks for your suggestion but that doesn't seem to work. That was the first place that I went to look and everything was checked. Just doesn't work but it does work in Safari.
If you are lucky Firefox may become more compatible with Lion, the tech guys know about the problem, but I am not sure what they are doing.
Keep an eye on other threads for any news e.g.
That's odd...I've been using Firefox, and it works for me. Did you change the options in the dropdown box in the Swipe between pages box? (see picture)
Did you guys also change the swipe between full-screen apps option to be something other than "swipe with three fingers"? I don't know if that makes a difference, but just a thought...
@ejhutch9125 I have that selected. It only works with Safari not FireFox...Bummer. But I think they are working on it and we will be good to go soon.
Ok I figured it out! You have to go to system preferences
