User Agent: Mozilla/5.0 (X11; Ubuntu; Linux i686; rv:15.0) Gecko/20100101 Firefox/15.0 Build ID: 20120825192214 Steps to reproduce: Firefox 15 beta and Nightly 18; Cyanogenmod 9 latest nightly on HP Touchpad (tenderloin). Watching this old demo (december 2011) of Firefox on Android tablets I notice gestures for forward, back browsing and opening/closing the tab bar. https://www.youtube.com/watch?v=UDTmkFIssKU Actual results: These gestures don't work, I can't find any swipe gestures except double-tap and pinch-to-zoom that work in Firefox on android Expected results: two or three finger swipe should browse forward/backward, a swipe in/out at the left edge should open/close the tab bar.
