* There is a new about:config option for keeping track of the max number of service errors to occur before disabling the service called app.update.service.enabled.
* When app.update.service.errors reaches app.update.service.maxerrors, or 10 if maxerrors does not exist, the service will be disabled and app.update.service.errors will be reset to 0.
== Configuration INI ==
A configuration INI setting can be used to optionally default the service installation off. This is useful for silent installs.
