Rated 3 out of 5 stars
Should be competitive/comparable with other users in some way possibly also stating which OS they run. about:cheevos is broken for me. I assume the achievements will be listed there. Information on what the achievement was for and what uses performing that action has would be great for newbies. Maybe even being able to comment on the achievements (preferably without registration) people could ask related questions and receive some help. Achievements for browsing accumulate browsing time would be cool as well. You could really fluff this addon out and hopefully add to the growth of Firefox by attracting new crowds for different reasons than before.This review is for a previous version of the add-on (1.3).
