Flash Player 10.3 introduces auto-update notifications for Mac OS X. If you’d like to disable those for your managed clients (because you are distributing these updates via munki, for example), install this package:
DisableFlash10AutoUpdate-1.0.pkg.dmg
This package installs a file at /Library/Application Support/Macromedia/mms.cfg with the following contents:
AutoUpdateDisable=1

Thanks to Patrick Fergus for the tip.
Update 02 July 2012: updated the link for the package.
Managing OS X 
That’s awesome. Thanks for posting this, Greg. Does anyone know how to disable auto updating for Firefox?
Sure. There are several posts on this blog about that. Search for “Firefox”.
Create ‘local-settings.js’ file in ‘/Applications/Firefox.app/Contents/MacOS/defaults/pref/’ with contents
pref(“general.config.filename”, “mozilla.cfg”);
pref(“general.config.obscure_value”, 0); // use this to disable the byte-shift
Create another file “mozilla.cfg” in ‘/Applications/Firefox.app/Contents/MacOS/’ with contents
// This file sets some prefs for use at MyOrganization
// and locks down some other prefs.
//disable application updates
lockPref(“app.update.enabled”, false);
lockPref(“app.update.autoUpdateEnabled”, false);
lockPref(“extensions.update.enabled”, false);
lockPref(“extensions.update.autoUpdate”, false);
lockPref(“browser.search.update”, false);
Thanks for the PKG !
Thanks for this handy information, and all the other hand information found on this site.
Thanks Greg! You always provide needed info. I wish Adobe just does plist like a good Mac application. That would make life easier.
