If installing from the addons.mozilla.org, use the following URL (substituting SHORT_NAME from the URL on AMO), https://addons.mozilla.org/firefox/downloads/latest/SHORT_NAME/latest.xpi.

| `install_sources` | Each item in this list is an extension-style match pattern. Users will be able to easily install items from any URL that matches an item in this list. Both the location of the *.xpi file and the page where the download is started from (i.e. the referrer) must be allowed by these patterns. This setting can be used only for the default configuration.
| `allowed_types` | This setting whitelists the allowed types of extension/apps that can be installed in Firefox. The value is a list of strings, each of which should be one of the following: "extension", "theme", "dictionary", "langpack" This setting can be used only for the default configuration.
| `blocked_install_message` | This maps to a string specifying the error message to display to users if they're blocked from installing an extension. This setting allows you to append text to the generic error message displayed when the extension is blocked. This could be be used to direct users to your help desk, explain why a particular extension is blocked, or something else.

### SanitizeOnShutdown (Selective)
Clear data on shutdown. Choose from Cache, Cookies, Download History, Form & Search History, Browsing History, Active Logins, Site Preferences and Offline Website Data.
-**Compatibility:** Firefox 68, Firefox ESR 68\
+Previously, these values were always locked. Starting with Firefox 74 and Firefox ESR 68.6, you can use the `Locked` option to either keep the values unlocked (set it to false), or lock only the values you set (set it to true). If you want the old behavior of locking everything, do not set `Locked` at all.
