Two Finger Swipe - any thoughts on this?

@gomita, I really like the idea and functionality of your add-on Three Finger Swipe. Thank you for developing it. But I think it could be easier and more intuitive to use (especially for people with fat fingers and small screens like me), so I took the freedom and forked your project, resulting in https://github.com/averageapps/twofingerswipe.

It changes the following aspects:

• Replaced all threes with twos... More precisely, the add-on now listens to two finger gestures, which are easier to produce in my opinion
• Reversed left/right tab swipe default behavior. This is more intuitive since most modern touch interfaces interpret movements in this reversed way.
• Changed compatibility settings to the current firefox versions
• Added some information about Three/Two Finger Swipe to the bootstrap.js and LICENSE.txt
• Unfortunately I had to remove all Japanese strings for now, because I can't read them. (I could supply German strings in return, if needed.)

Unfortunately, I have no experience in Javacript and add-on development, so I could not change everything that I had in mind by now. However, I am planning to make the toast messages optional, for example. Optimally, the preferences should also be located inside about:addons, not in the general overflow menu.

I am not sure if I should publish this as a seperate add-on. It would of course be better to merge our projects and provide more options to the user.

What do you think about all this? I am open to any criticism and suggestions.

After using the 2 finger version for a few days, I understand now why you chose 3 fingers.

Apparently it conflicts with the standard pinch-to-zoom gesture if you are not careful with the movements.

Therefore in this form, my fork is pretty useless. Maybe I'll try to find out if this can be fixed.
