Easily the best of the non-recommended Android extensions so far. I used Simple Gesture pre Fenix and am so glad it works in Android again.

Only thing I can think of that would make it better is a "open link in background tab" double-tap function (might not be possible.)

EDIT: Double tap (or other gestures) already works for opening a link in a new tab! Friggin' awesome! Fantastic extension.

Holy crap, I cannot describe how useful this is. You are amazing. One handed operation is great, but if anyone else noticed—there's no forward button! Like no functionality for one in system UI OR Firefox! Luckily, our dev hero saves the day and many minutes of accidentally swiping to some random assigned action while navigating Firefox, and subsequently raging. Seriously utubo, thank you so much. <3

(sidenote: there are customizable simple gestures for opening a custom url, closing or opening a new tab, reloading, etc! imo should be implemented in every android os natively.)

It's the best add-on for Android！Thanks too much.

Thank you so much for this. It's a little finicky, but even just assigning a gesture to close a tab brings Firefox's usability much closer to Chromium's.

1，非常好用nice，主要手机端也流畅。(*^▽^*)
2，只是不知道为啥，搜索simple的时候，竟然没有出现这插件，火狐推荐的其他。输入完整的关键词才有，差点错过了(⊙o⊙)…

The add on provides swipe functionality that I missed from chromium browsers even supports extra gestures such as combinations. Thanks to developers. In order to use this extension on mobile, you have to use Firefox Nightly (for now). You can find instructions on reddit that would guide you through how to install them via add on collections method.

I can't stand Android's native gestures when using a browser, so after finding this addon, I was determined to figure out how to install it on my phone. It took a few hours and more effort than I expected, but it was worth it. I now have a forward gesture, and so much more. The only drawback is having to use Nightly, but that's not the developer's fault. I'm just grateful for the functionality I now have.

安卓完美支持

Excellent Addon, works great on mobile. Switching tabs stoped working sense the help update weach is a real shame. Now I use it for closing and opening tabs.

nightlyにて使用中。
ジェスチャーが使えないとfirefox使っている意味ないから使えて良かった。
ところで、次のタブ前のタブが使えなくなってました。
修正は可能ですか？

Works great in Firefox Nightly on Android. Thank you for building it.

Honestly this add on makes the browser so much more user friendly, really improved the experience a lot.
hoping to see this become available in the new version of Firefox daylight soon
