Unable to connect to websites which donot start with www I have created hotspot from my Andriod mobile and using Internet on laptop Windows 7 but I'm unable to connect to websites which don't start with www..

The error:


  If your computer or network is protected by a firewall or proxy, make sure that Firefox is permitted to access the Web


Should the settings be done on mobile or laptop? What should I change?

Note I am using mobile data. Websites starting with www. are working fine. The problem doesn't occur on my phone. Also everything is OK when my laptop uses LAN.

Mobile(alone with data) and laptop(alone with LAN) works fine , it is only when mobile hotspot is used in laptop, i am not able to access websites which don't start with www.
How do I prevent Firefox to use: www.foo.bar instead of foo.bar? suggests setting browser.fixup.alternate.enabled to disabled to be a working solution

Turning off Domain Guessing


In the address bar, type about:config and press Enter
The about:config "This might void your warranty!" warning page may appear. Click I'll be careful, I promise! to continue to the about:config page. (There's no warranty with Mozilla so I suppose this is to just a warning joke)
In the Search field, type fixup.Double-click the browser.fixup.alternate.enabled preference to set its value to false. 

Changing the prefix (to www )


In the about:config page, double-click the browser.fixup.alternate.prefix 
In the pop up menu enter www.  ( if that doesn't help try www without . )
