Today I submitted version 0.7 of the safe add-on. This was not a version with additional features, but rather a version that collects stats from users who uninstall the add-on.
I mainly did this because I wanted to know more about why only a small percentage of users who downloaded my extension continued on using it. How long have they used the extension? What options have they enabled (if any)? Where are my users coming from? I stopped short of asking people to complete a feedback form, instead opting to just send data to my server. It’s relatively anonymous, except for the IP address which gets recorded.
Unfortunately, this doesn’t really give me useful statistics from people who stay with my add-on. Which is still useful. My best hope is that it’ll answer at least one of my questions that it was set out to answer.
