How to stop homepage in Firefox from being changed

To stop users from changing the homepage set in Mozilla Firefox isn't as straightforward as it for IE.

Open notepad or any text editor and place the code below in, change the URL to what you want the homepage to stick to.

//
lockPref("network.proxy.type", 0);
lockPref("browser.startup.homepage", "http://www.google.co.uk/");

Save this file as mozilla.txt.

Browse for mozilla.txt for the input file and set the output file to the root directory of Firefox (where 'firefox.exe' is located. Name it mozilla.cfg, set the offset to 13 and click 'go'.

The configuration file should be created.

Browse to the Mozilla Firefox root and then the greprefs sub directory.

Edit the all.js file in notepad or any text editor and add the following code at the end.

pref("general.config.filename", "mozilla.cfg");

Change file type to all types and save.

If you get problems saving the js file or the cfg file change the directory to not be read only.

Close all instances of Firefox and see if this has worked.

You can use 'about:config' in the address bar to change a few things in Firefox to speed browsing up but unfortunately for this problem I couldn't see an option as simple.

Hope this helps.
