I have deployed firefox using local-settings.js, mozilla.cfg and override.ini files. local-settings.js : pref("general.config.obscure_value", 0); pref("general.config.filename", "mozilla.cfg"); mozilla.cfg : //Firefox Default Settings // set Firefox Default homepage pref("browser.startup.homepage","https://www.yahoo.com"); // disable default browser check pref("browser.shell.checkDefaultBrowser", false); pref("browser.startup.homepage_override.mstone", "ignore"); // disable application updates pref("app.update.enabled", false) // disables the 'know your rights' button from displaying on first run pref("browser.rights.3.shown", true); // disables the request to send performance data from displaying pref("toolkit.telemetry.prompted", 2); pref("toolkit.telemetry.rejected", true); the homepage is getting set properly, but the user is not able to change the homepage later on. plz tell what changes i need to make so that users should be able to change the homepage according to their choice any time.

// set Firefox Default homepage 
defaultPref("browser.startup.homepage", "data:text/plain,browser.startup.homepage=https://www.yahoo.com");
