I really like the interface for setting the gestures and they work great. Unfortunately, about once a month, all settings reset to default...I highly customize mine so each time it's about 10 minutes setting everything back to normal. I understand this may be related to firefox sync. Unfortunately, yeah I use firefox sync, this app is for firefox...none of the other apps I use have a problem with sync, are you sure there's nothing you can do about this?
it's not worth the frustration. Moving on.
