3. Now create another Notepad file and enter the following text: pref(“general.config.filename”, “Mozilla.cfg”);

(Make sure you include the semi-colon). Name the file ‘local-settings.js’ and save it. Now, copy and paste this file at Mozilla Firefox – default – pref folder.

Finally, restart Firefox and your home page should now be locked against changes. You can unlock it by deleting the contents of the mozilla.cfg file. (source)
