关于这个附加组件
While it used to be possible to disable add-on compatibility checking entirely, by setting the
extensions.checkCompatibility preference to false, it is now necessary to set a different preference for each new application version. This add-on re-enables the functionality of extensions.checkCompatibility irrespective of the current application version and disables checking by default. Checking can be re-enabled by disabling the add-on (which can be done without a restart) or by toggling the preference.
