So far I have been just playing around with the Addon SDK and making tools for my own use.
I had in mind the idea to possibly try to do something like one of those extensions that adds a profile theme to your Facebook profile, as well as letting others with the extension see your theme when they visit your Facebook profile.
I'm just kind of thinking out what I may do, and what I was wondering is - I know the addon will have a unique ID, but is there anything inherent I can use to identify each unique Addon user? I.e. to tie them to the stored data with their theme information?
If anyone has experience with this - how did you approach it?
Maybe I could set a cookie as the Addon that lasts a year or something, and then keep resetting it each time the browser is opened, and hope for the best?
