This change will go live on the site later this week.<\/p>\n<p>The user count is a very important part of AMO. We show it prominently on listing and search pages.

This means some add-ons with high disable rates have a higher ranking than they should.<\/li>\n<li>It&#8217;s an average over a period of several weeks. Add-ons that are rapidly growing in users have user numbers that are lagging behind.<\/li>\n<\/ul>\n<p>We&#8217;ll be calculating the new average based on enabled installs for the past two weeks of activity. We believe this will reflect add-on usage more accurately.<\/p>\n<h3>What it means for add-on developers<\/h3>\n<p>We expect most add-ons to experience a small drop in their user numbers, due to the removal of disabled installs. Most add-on rankings on AMO won&#8217;t change significantly. This change also doesn&#8217;t affect the detailed statistics dashboard developers have access to. Only the number displayed on user-facing sections of the site will change.<\/p>\n<p>If you notice any problems with the statistics or anything else on AMO, please let us know by <a href=\"https:\/\/github.com\/mozilla\/addons-server\/issues\">creating an issue<\/a>.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>We&#8217;re changing the way we calculate add-on usage statistics on AMO so they better reflect their real-world usage.
