Allow FireFox Browser To Run Localhost Web Sever

This isn't an issue with Google Chrome browser, but Firefox will not allow you  to run local website  localhost.

If you try to run a local webserver on http://localhost.com, Firefox will automatically convert the URL into http://www.localhost.com. This is really annoying.

Lucky, there is a setting in Firefox to turn the feature off.

To disable this ‘feature’ do the following:

• Type about:config in the Firefox browser bar
• Type browser.fixup.alternate.enabled in the search box that appears
• Double click on the browser.fixup.alternate.enabled will turn it to false
