Using this on a surface tablet, works perfectly. The animation helps you to not activate the swipe action by accident.

Can use some improvement

1. Settimeout maybe 300ms after page load? So it won't accidentally move forward or backward in an empty page?

2. lock the vertical scrolling when showing forward/backward animation

3. show(or not) animation based on the history

4. Don't trigger when more than one finger detected, maybe a 10ms window for detection?

I really hope I can control trigger sensitivity, I often mis-trigger.
Other than that a great extensions.

refresh swipe is too sensitive to the point of being unusable

It's a great find for any person who wants to benefit the full potential of a touchscreen.
Seems to be the only viable option, too.
I would really not want to break the five star rating of this marvelous extension; but as another user has mentioned, it is a bit too sensitive. Especially the refresh swipe/gesture, which does give one a tough time when the only desire is to scroll down.
It would be great to have a settings page, in which one could somehow customize the gestures/swipes.

11/21/2024 update:
I believe I have narrow down the bug:
The backward will trigger if i use touch screen immediately after a page is loaded, no matter the gesture. If i wait for a second so the page is fully loaded this won't happen.

This add-on seems to work as expected and add touch screen back and forth with single finger swipe to Firefox on Linux. It even shows an arrow for confirmation when you start swiping just like on Google Chrome.

Tested on Fedora Gnome, Microsoft Surface Go 2 Core m3.
