There has been confusion about which Build ID is correct; in the latest two nightly forum threads http://forums.mozillazine.org/viewtopic.php?f=23&t=2005457&start=73 & http://forums.mozillazine.org/viewtopic.php?f=23&t=2006153&start=60. FWIW In searching to see if this is a know bug (or an expected result), I have found bugs talking about the possibility of dropping the Build ID completely. Reproducible: Always Steps to Reproduce: 1. Open the application.ini file in the Minefield application directory, and look at the [App]->BuildID= 2. Open 'about:support' and check 'browser.startup.homepage_override.buildID', or in Minefield directory look at Firefox.exe->file Properties->Version->Build ID. 3. The Build ID in step #1 & 2 are different. Actual Results: The Build ID in "application.ini" and "about:support->browser.startup.homepage_override.buildID" (or Firefox.exe->file Properties->Version->Build ID) are different. Expected Results: The Build ID should match? If not which Build ID is real? See attachment.
Check Build ID in red circles. One (or 2, if you count crash ID) in "application.ini" file. One in "about:support" and a matching ID in "Firefox.exe->File properties->Version->Build ID".
I can confirm this on Mozilla/5.0 (Windows NT 6.0; rv:2.0b7pre) Gecko/20101006 Firefox/4.0b7pre ID:20101006041601 application.ini file shows: BuildID=20101006041601 about:support browser.startup.homepage_override.buildID shows: 20101006031215 On my PC there's no "Version" tab on firefox.exe > Properties so I can't really tell that one.
http://kb.mozillazine.org/Browser.startup.homepage_override.mstone : "When a user starts up their browser, this preference is examined. If its value differs from the browser’s current milestone, then the user is redirected to the homepage specified in startup.homepage_override_url and this preference’s value is updated to the current milestone." So according to that (not authoritative), the current behavior is correct on first start of a new build, but the build id should update on restart and doesn't. Note that the homepage_override.buildID pref is sort of "internal use", and is not intended to always be the current build id, so probably shouldn't be recommended as a source of support info. I suggest morphing the summary to make the bug about the pref not updating as per the knowledge base clip, and let somebody who knows decide if that's intended or a bug.
Forgot to say: Is "Build Config" the right component (he asks sceptically)? And platform is probably "all", but I can only speak for vista. Mozilla/5.0 (Windows NT 6.0; rv:2.0b8pre) Gecko/20101007 Firefox/4.0b8pre
Ignore me completely. Just noticed that kb reference is to the wrong pref--milestone vs build id. Sorry.
Can't reproduce with 4.0b7 release on mac. Probably something to do with PGO on windows.
Confirmed with the latest win32 nightly using XP. application.ini & aus query: 20101116042306 firefox.exe props/browser.startup.homepage_override.buildID: 20101116031541 (Same for xul.dll, updater.exe, so probably all the executables) In the nightly build log  there are d:/mozilla-build/python25/python2.5.exe /e/builds/moz2_slave/mozilla-central-win32-nightly/build/toolkit/xre/make-platformini.py --buildid=20101116031541 --sourcestamp=a42e9b001bc8 --sourcerepo=http://hg.mozilla.org/mozilla-central /e/builds/moz2_slave/mozilla-central-win32-nightly/build/config/milestone.txt > platform.ini d:/mozilla-build/python25/python2.5.exe /e/builds/moz2_slave/mozilla-central-win32-nightly/build/toolkit/xre/make-platformini.py --buildid=20101116042306 --sourcestamp=a42e9b001bc8 --sourcerepo=http://hg.mozilla.org/mozilla-central /e/builds/moz2_slave/mozilla-central-win32-nightly/build/config/milestone.txt > platform.ini I don't see where that gets into application.ini so that may be a red herring. Ted/Khuey: is this worth fixing ?  http://tinderbox.mozilla.org/Firefox/1289905344.1289915617.3118.gz
