User Agent: Mozilla/5.0 (Windows NT 6.1; rv:41.0) Gecko/20100101 Firefox/41.0 Build ID: 20151014143721 Steps to reproduce: In windows 7 SP1, patches until 28 Oct 2015 I press the button update-chronik in Extras->Einstellungen->Erweitert->Update. (extras->preferences->advanced->update) Actual results: I see a update log which is incomplete/inconsistent to the actual version installed. This is true for all users, who did not initiate the Mozilla update. Only the user who initiated the update (automatically or manually) gets a log which is consistent with (the last) update. All other users see a incomplete/inconsistent log. Expected results: I would expect a consistent update log irrespective of the actual user. All users should see the same update log since they all use the same Version of Mozilla, which has the same update history! I consider this bug only a cosmetic problem which is a bit confusing. However, Help->About delivers the correct, actual version of Mozilla for any user.
