Hi, dears all
I want to build an embedded system which uses triple axis acclerometer to control Mozilla Firefox's goback function.
I've found an extension using middle click to go back:
https://addons.mozilla.org/zh-tw/firefo ... o-go-back/
All I need is write a .c script to load the 3-axis data and feed them to js file.

Following the guide(http://hublog.hubmed.org/archives/001606.html), I tried to figure out how Firefox's extensions work and where the javascript and xul file in xpi are extracted to.
The guide said I should find a directory in /extension folder but only find one xpi file (no file and directory concealed).
Please tell me where can I find those js and xul file to hack them?

I use Firefox 23.0 on Ubuntu and I've already installed "Middle Click To Go Back 3.3".
sorry but this terminal doesn't support chinese typing. orz
