This is the first plugin that I found mentioning about mobile support so I'm very pleased to try it on Firefox for Android :)
The swipe feature does works! but it makes zooming in-out harder and it doesn't very make sense since the picture didn't slide along but fade to a new picture.
The black overlay were maximized perfectly so there are no flickering while zooming in-out which is very good!
Screen transition (between vertical/horizon) isn't smooth for a duo-core phone.
