Generally works well, tried to recreate Chromes Touchscreen gestures for previous/next page with a single finger horizontal swipe. Unfortunately there is no visual feedback whatsoever when the gesture has worked which is unfortunate since the gestures don't work on some websites or are not executed precisely enough. Some visual feedback would be awesome.

I was looking for something to swipe back/forward on a page using Windows 10 on Surface Pro 4 and this plugin dies that. You can configure the plugin to only use one finger if two is tricky to use.

For any reviewers that are giving this extension one star because it doesn't work, if you're on Linux be aware that FF's ability to sense multi-touch input in Linux is non-existent, hence not this addons fault. Extension works in Windows and I had managed to get used to it, though, honestly it was a bit of a pain in the behind to get it to recognize the gestures. The dev was considerate enough to provide a little app to practice your gestures on. I'd really recommend you use it. My best piece of advice for that is to keep your two fingers together when doing a gesture as it requires a perfect parallel movement. I would also try to keep it simple. Don't bother mapping 8 macros for the eight directions the addon gives as it it's either not really good at recognizing the diagonals or I'm not precise enough for it. Map for two things only (let's say go back, go forward) and map one side for first macro and the other for the other macro. It starts working very consistently at that point.

All in all, it's a really good plugin and I was sad to see it go when I migrated to Linux, but it's also a little rough around the edges and can use a bit of improvement in it's ability to detect gestures (perhaps make the two finger detection algorithm less strict on how parallel the line traced by the two fingers has to be). Dev. If you feel like it and are able to, it would be really cool to have single finger gesture support by having the addon detect motions on the edges of the browser window.
