Sync portable and non portable versions?

I have the regular Firefox installed on my laptop and Firefox Portable on my USB key. I'm more often using the laptop one and I was wondering if there was a way I could transfer or sync all my bookmarks, addons, settings and passwords between the laptop and usb drive? Is this what Firefox sync? I had a quick look at it but it I'm not sure if it sync addons though. Thanks for any help and this project has really improved and grown since the days of just Portable Firefox!
