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
