Created attachment 574149 [details] Incorrect stats for the RXM add-on. If you go to https://addons.mozilla.org/en-US/firefox/addon/remote-xul-manager/statistics/?last=90 now, you'll see that the Top Applications section has very incorrect data, which I am attaching as a screenshot. This particular add-on has ~24K ADU. However, the Top Applications chart shows Firefox 6 as the top application, with 2.4K ADU, claiming it is 46%. Firefox 8 is shown as only 9%. If you click in the "More applications" link, this page shows the right data. This is happening with many, perhaps all add-ons, so I'm marking it as major.
Potch thinks this is a dupe of bug 697362 and he's working on that one.
