Has anyone else noticed their 1 finger back/forward gestures no longer working in Chrome? I have tried the gestures on other applications such as Safari and Mission Control, they are all still intact.
Make sure you enable: System preferences > Mouse > Swipe between pages
AND OPEN A NEW TAB in Chrome
If you had it working before but then it stopped working suddenly (usually after an OS / Application update) you might just have to uncheck / recheck the "Swipe between pages" option. That should solve it.
There is a bug report already on the Chrome forums. Check it out here and add your info too.
It seems to be a sporadic problem; I have the issue every hour or so, but my colleague doesn't get it at all.
