Solution: loading localhost under Firefox in Windows 7 is too slow

I like debugging in Firefox. The default debugging tool is very convenient, and firebug is even more famous...

However, since Windows 7 was used and Firefox was used to open the website under localhost, loading was too slow. Finally, a solution was found:

--------------------------------------------------------------------

1. Enter about: config in the firfox address bar and press Enter 〕.

2. Enter V6 in the filter to find network. DNS. disableipv6 and double-click to change the value to true.

OK. Try again on Firefox!
