Update-MozillaFirefox tries to write several Firefox-related files, namely "firefox_current_versions.json", "firefox_release_history.json", "firefox_languages.json" and "firefox_regions.json" at Step 7. If the script has advanced to the updating phase, at Step 14 an Install Configuration File (firefox_configuration.ini) is also written to $path, where, for instance, the automatic Mozilla Maintenance service is disabled and the default shortcuts are enabled.

If Update-MozillaFirefox is run without elevated rights (but with a working Internet connection) in a machine with an old Firefox version, it will be shown that a Firefox update is needed, but Update-MozillaFirefox will exit at Step 12 before downloading any files. To perform an update with Update-MozillaFirefox, PowerShell has to be run in an elevated window (run as an administrator).

If Update-MozillaFirefox is run in an elevated PowerShell window and no Firefox is detected, the script offers the option to install Firefox in the "Admin Corner", where, in contrary to the main autonomous nature of Update-MozillaFirefox, an end-user input is required for selecting the bit-version and the language. In the "Admin Corner", one instance of either 32-bit or 64-bit version in the selected language is installable with Update-MozillaFirefox – the language selection covers over 30 languages. +

In the update procedure itself Update-MozillaFirefox downloads a full Firefox installer from Mozilla, which is equal to the type that is already installed on the system (same bit version and language). After writing the Install Configuration File (firefox_configuration.ini at Step 14) and stopping several Firefox-related processes Update-MozillaFirefox installs the downloaded Firefox on top of the existing Firefox installation, which triggers the in-built update procedure. @@ -144,8 +144,7 @@

  • Update-MozillaFirefox is designed to update only one instance of Firefox. If more than one instances of Firefox are detected, the script will notify the user at Step 5, and furthermore, if old Firefox(es) are detected, the script will exit before downloading the installation file at Step 15.
