Localhost not working in chrome and firefox

I faced the same issue and the complete solution is to set to false(uncheck) the "Automatically detect settings" checkbox from Lan Area Network( the same window as for Bypass proxy server for local address )

Finally I found the solution ... It's very easy

1. Go to the LAN settings (In Chrome : Tools -> Options -> Under the hood -> Change Proxy setting -> LAN Setting)

2. There will be a checkbox for "Bypass proxy server for local address"

3. Tick the checkbox.

Done!

On Mac/Apple: Chrome uses system preferences for localhost exclusion:

1. Go to System Preferences -> Network -> advanced -> Proxy settings

2. Add 'localhost' at the bottom where it says: 'ignore proxy settings for these hosts and domains' (Exceptions are separated by a comma)

For all browsers,

• Open internet Options (or Internet properties)
• Go to connections tab
• Click on LAN Settings
• Tick Use proxy server for your LAN
• Tick Bypass proxy server for your local address (Don't change the port number)
• Click on Ok

Now you are good to go. :)

If you are using windows system:

please check the file

C:\Windows\System32\drivers\etc\hosts

and add line such as:

127.0.0.1 localhost
