Update:Native smooth zoom is starting to appear in newer Firefox builds. Try enabling it by going to
about:config in the url and setting
apz.allow_zooming to
true. If that works for you then you don't need to use this plugin :)
---------
This extension adds support for smooth zooming with the pinch gesture on a trackpad. It's been designed to match the behavior of Chrome and Safari.
Make sure all the "
browser.gesture.pinch" settings in
about:config have been reset to empty, otherwise it wont work properly
