After going through a lot of search hits, I still haven't found a reliable solution to integrate addons into Firefox and have them set up from an unattended XP disk. I did manage to find a piece of software called JonnyboysTools_v0.103, but I'm still not quite sure how it works; my guess is it reads preferences from the current system, but it doesn't ask for any installation files either from Firefox or addons.
I suppose this is the best sub-forum to pose this question, so I was wondering if there was any progress into this matter.
Thank you for your thoughts,
Edit: I managed to make an off-line install with JonnyboysTools_v0.103, and am testing the nLite addon on VirtualPC. Will be back with results.
