Is there a way to avoid the "You've just upgraded to version x.xx" page (due to deployment on frozen machines)?
As described, I want to deploy Firefox to machines that have Deep Freeze installed on them, but due to the frozen status, these machines will keep displaying the "new version" page every time they are reset and Firefox is open. I can manually go around, thaw them, close the page and then freeze them again, but this takes a lot of time and kind of defeats the purpose of pushing installs out to the PCs.

This is controlled by a hidden preference browser.startup.homepage_override.mstone, setting it to ignore will stop Firefox displaying the "You've been updated" page. For more details on that preference see http://kb.mozillazine.org/Browser.startup.homepage_override.mstone
I have never tried this, but locking that preference by using the method shown in the Locking preferences article should work. Add the following to the lock file as shown in that article.
//
lockPref("browser.startup.homepage_override.mstone", "ignore");
If the profile folder is removed and a new default profile gets created then you can also use the file user.js to initialize prefs.
You can place that file in the default template location:
C:\Program Files\Mozilla Firefox\defaults\profile\
See also http://kb.mozillazine.org/user.js_file (user.js)
user_pref("browser.startup.homepage_override.mstone", "ignore");
