Waterfox (Not Classic) Portable

I and Im sure many others would really like if this was added. I have tried the illegal site release and just dumped over the latest G6 files and overwrote the 4.1.2.1 version files and it worked but I dont like the layout and they have some things locked down like app updates and custom stylesheets (userChrome.css file) dont work even with the flag forced to true.

Please!
