Various modules provide shared utilities to the other components:

UrlbarPrefs.sys.mjs

// Always use browser.urlbar. relative branch, except for the preferences in
// PREF_OTHER_DEFAULTS.
UrlbarPrefs.get("delay"); // Gets value of browser.urlbar.delay.

Note

Newly added preferences should always be properly documented in UrlbarPrefs.
