Please add duplicate current tab.
Edit: nice, this script works.
Edit2: unfortunately the add-on doesn't work on my Windows tablet.

Great add-on! Though U-R and U-L for next and previous tabs look more intuitive for me.

Android版Firefoxでは反応が悪いことが度々ある。
本来Android向けに作られているはずなのになんでやろうか…
Windows版Firefoxに強制インストールしてみたが、Windows版Firefoxでは問題なく動いている。

Давно искал. Спасибо за труды!

Fantastic add on. Excellent work. I was wondering about a few additions. Is there any way to add in a function for pasting text directly into the URL bar? I was trying to see if I could do a custom gesture with JavaScript but I'm not very good with JS, sorry.

Edit 11/27 Sending my thanks for the speedy update. I have been using it once you first released it and it works very well. All the best,

Hope to see this addon back on firefox android soon.

This is a great AddOn for FF on Android - finally it's possible to use Firefox almost as fast as on desktop. Thank you so much!
Two suggestions though:
Can you implement the possibility to block gestures on certain pages in the future? I know I can enable/disable it manually. But I use e.g. https://www.qwant.com/maps/ in the browser quite often, and of course it would be best to disable SG automatically on such pages, where you e.g. push a map around.
Another question: I use 'new tab' gesture very often and it really bugs me that I afterwards have to click once more on top into the address bar to start typing or to even see the default suggestions of firefox. Would it be possible to automatically focus the address bar?
Thanks a lot!

Couldn't get it to work on v68.1
Just as Grumbely said, the page just scrolls.
Where the reck am I supposed do do the gestures?

Edit: extension is blocked in *.mozilla.org
Works great on other sites

「タブを閉じる」に「D-R」を設定していますが反応が非常に悪く5回に1度ぐらいしか成功しません。感度調整をいろいろ試しても変わらず。他のジェスチャーは概ね問題ないのですが、なぜかこの組み合わせだけは相性が悪いようで、初期のバージョンから使っていますが未だにこの現象だけは改善されません。

Not working as of 68.0.2. Also, there is no explanation anywhere of how to actually use the plugin. The gestures are only listed as strings of letters (such as “D-L-U”) representing cardinal directions (which is not explained, you need to have used similar plug-ins which do explain it) but no explanation of where or how to execute these gestures.

works perfectly but the setting is gone occassionally for no reason so I have to customize my setting over and over again it really annoying what should I do?

Doesn't suppress context menu on Linux.

Please implement an option to open the tab list with a gesture.

Wow, so powerful! Such a good Firefox Android navigation experience.

Works perfectly. Easy to set up and customize.

That's just great!!!!!! A must have. Thx a lot for great idea and its execution

Best productive add-on for Firefox!

Working on 66

But the "timeout" setting is not working as intended.

imo the timeout timer should reset it self if the user's finger is still moving

Thus 1000ms timeout means "if the user's finger stop moving for 1 second, stop gesture detection"

The current logic is, however, "I gave you 1 second to finish your gesture, no matter the gesture is super simple that you need to wait 800ms after finished it or it's super complex that you can barely draw half of it in 1 second", this is counter-intuitive.
