Oh, sorry.
I supported two-finger swipes, but forgot to support two-finger taps.
Might take some time.

I create a new issue.

thanks.

> Please add gesture for switching tabs.
The API provided by Firefox is unstable, but you can use it by turning on “Enable experimental features” on the settings page.

> And maybe add two finger swipes.
Sorry, it will take some time to work on this.
I'll add it to the issues list.

v3.27 supports this.

This needs clip-board access though for custom gestures (=user script).
I will summarize the permissions.
Thank you for your review

I done. (see About Extensions)

Sorry, Firefox for Android does not support the Bookmarks API for add-ons.😢
Thank you for your review.

> the notifications including timeouts could be hidden.

I fixed to hide the timeouts when 'Diaplay Command' is disabled in v3.12.2.
Thank you for your review.
