This small but very useful program somehow manages a virtual instance of your host file.
What does that mean for you??
With the click of a button you can switch from your development server to your live server (or any number of other servers). No more closing the browser > updating your host file > Flushing your IP Cache > restarting your browser > clearing the browser cache > HOPING that it worked. Now it is just two clicks > refresh… and you’re looking at a completely different server.
If you develop web sites and ever need to toggle between a live and development sites… get this Firefox Plugin right now. It will save you hours of trouble.
