If you have installed WAMPServer and taken IE as the default browser and want to change it that is very easy.
Make a backup of `\wamp\wampmanager.conf` just in case.
Edit `\wamp\wampmanager.conf`
Locate this parameter,
navigator = "whatever is there currently"
its at the top of the file about line 7 and change it to
navigator = "C:/Program Files/Mozilla Firefox/firefox.exe"
Make sure thats where your Firefox is installed and note the use of the UNIX `/` forward slash and not the DOS `\` backslash.
While you are in that file you might also like to change the default editor from notepad to a decent one that you have installed or maybe use notepad++. Its good and free. In that case also change this parameter
editor = "c:/program files/notepad++/notepad++.exe"
