Using Settings in Firefox

Question

How do I access user preferences in Firefox? I have the following code:

var control = document.getElementById(control_id);
if (control) {
    control.setAttribute('color', nsPreferences.copyUnicharPref(prefstr, default_val));
}

But when I run this, I get the following:

Error: nsPreferences is not defined
Source file: chrome://backgroundtoggle/content/options.xul
Line: 9

I'm having trouble processing Mozilla documentation. How to do as I want?

Answer 1

It looks like you need to include nsUserSettings.jsin your file .xul:

<script type="application/x-javascript" src="chrome://global/content/nsUserSettings.js" />

It is defined here nsUserPreferences.

See here for an example options.xul. The tag scriptmust be the first child prefwindowto make sure that it loads before your own code.
