i using this addon from the beggining, when its appears on Mozilla website. last week, i lost acces to my account in one of popular games(i play in this game over 3 years), and i asked for help Support. one important thing i must admitt, i was never a premium user, always as free. Support answered immediately. they create again my lost account, and i again have access to my game. after 5 years, they deserve to leave feedback. THIS IS REALLY GOOD JOB GUYS. THANK YOU AGAIN. especially you, Dave, and your database guru :D
wish you best.
