How to make Internet Explorer or Netscape Navigator your default browser:
During the installation both Internet Explorer and Netscape Navigator browsers will ask whether you want them to be your default browser. If you tell them not to prompt you to perform that check again in the future, here's how to make them do it again:
Explorer 5.x
Select "Tools | Internet Options..." from the main menu.
Change to the "Programs" tab
Enable "Internet Explorer should check to see whether it is the default browser"
Click "OK" and restart Internet Explorer
Explorer 4.x
Select "View | Internet Options..." from the main menu.
Change to the "Programs" tab
Enable "Internet Explorer should check to see whether it is the default browser"
Click "OK" and restart Internet Explorer
Communicator 4.x
Open the "prefs.js" file located in "\users\" using a text editor such as "Notepad"
For example:
"C:\Program Files\Netscape\users\prefs.js"
Make sure that the following line has the value "false" or insert it to the end of the file if the line does not exist:
user_pref("browser.wfe.ignore_def_check", false);
Save changes to the file and restart Netscape Navigator
