Mozilla/5.0 (Macintosh; U; Intel Mac OS X 10.5; en-US; rv:1.9.1b3pre) Gecko/20090221 Shiretoko/3.1b3pre Ubiquity/0.1.5 ID:20090221020541 If Firefox is called via a path which contains a symlink the software update is grayed out inside the help menu. That happens due to missing permissions. As result canUpdate fails: AUS:SVC UpdateService:canUpdate - unable to update. Exception: [Exception... "Component returned failure code: 0x80520015 (NS_ERROR_FILE_ACCESS_DENIED) [nsIFile.create]" nsresult: "0x80520015 (NS_ERROR_FILE_ACCESS_DENIED)" location: "JS frame :: file:///C:/Programme/Mozilla%20Firefox%203.1/components/nsUpdateService.js :: anonymous :: line 1607" data: no] Steps: 1. Do a normal installation of Firefox 2. Create a symlink which points to "C:\Program Files" (see bug 456895) 3. Call Firefox via this symlink

This happens because the path is not under program files which is required on Vista to prompt for elevation. We might be able to just check if the user is a member of the admin group and not care if the path is under program files.

note: the error is an expected / handled exception for this case

This is a dupe of the other bugs to provide the ability to update when outside of program files on Vista or for that matter anywhere when running as a limited user on Win2K / XP which is bug 318855
