Having trouble with lockPref certain settings in Firefox4.

//Don't check for automatic updates:
lockPref("app.update.enabled", false);

// May want to enhance with:
//   lockPref("extensions.update.enabled", false);
//   lockPref("app.update.autoUpdateEnabled", false);

//Set proxy type to enable proxy.pac file:
lockPref("network.proxy.type", 2);

//Don't check if FF is default browser:
lockPref("browser.shell.checkDefaultBrowser", false);

//Disable FF4.x hardware acceleration:
//Doesn't look like these settings effect earlier vers.
lockPref("layers.acceleration.disabled", true);
lockPref("gfx.direct2d.disabled", true);

I've been trying to lock down some settings using a .cfg file in Firefox 4. The file contents are below. Here's what I did: * I created mozilla.cfg.txt with the settings displayed below. * I used the moz-byteshift.pl script to encode the file. * I put the file name reference into all.js and double checked the offset was 13. * I copied both files to the firefox prog folder and greprefs folders respectively. * I also deployed override.ini to stop the initial IE import wizard. Here's what I put in the file. What am I doing wrong? Let me know. Thanks. <pre><nowiki>//Don't check for automatic updates: lockPref("app.update.enabled", false); // May want to enhance with: // lockPref("extensions.update.enabled", false); // lockPref("app.update.autoUpdateEnabled", false); //Set proxy type to enable proxy.pac file: lockPref("network.proxy.type", 2); //Don't check if FF is default browser: lockPref("browser.shell.checkDefaultBrowser", false); //Disable FF4.x hardware acceleration: //Doesn't look like these settings effect earlier vers. lockPref("layers.acceleration.disabled", true); lockPref("gfx.direct2d.disabled", true);</nowiki></pre>
