I've been trying to reproduce the problem using builds from firefox.com.cn, however I don't know where to get older versions of the bundled addons such that I can check for addon updates in order to reproduce the problem.
What I've observed is that when I do an update from 6.0.2 to the latest version, there is a dialog for addon updates, which it then downloads and the application starts up fine with no missing addons. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to thunderbird in Ubuntu. https://bugs.launchpad.net/bugs/861664 Title: Upgrading Firefox/Thunderbird when an add-on update is waiting to be installed hides the add-on Status in The Mozilla Firefox Browser: Fix Released Status in “firefox” package in Ubuntu: Fix Released Status in “thunderbird” package in Ubuntu: Fix Released Status in “firefox” source package in Oneiric: Fix Released Status in “thunderbird” source package in Oneiric: Fix Released Bug description: This affects users by temporarily hiding their addon until another addon update/install prompts the addon manifest to be rebuilt.
