Description

This API method allows user script authors to persist simple values locally.

Strings, Booleans, and Integers are currently the only allowed data types. Values are saved in the Firefox preferences back end and can be manually changed by typing about:config in the address bar and searching for the preference name greasemonkey.scriptvals.namespace/name.foo.

The Firefox preference store is not designed for storing large amounts of data. There are no hard limits, but very large amounts of data may cause Firefox to consume more memory and/or run more slowly.
