Switch your host/IP mappings in real time without editing your hosts file

LiveHosts: Dynamic Host/IP Remapping Firefox Add-On
"LiveHosts" is a specially designed Firefox extension. Its function is to enable users to simulate hosts file modifications by redirecting specific domains to selected IPs, along with an additional Host header. The unique feature of LiveHosts is that your browser's address bar reflects these redirections by displaying the hostname right after the IP. This saves the user from the trouble of manually editing the host files for each switch, streamlining the procedure and ensuring a smoother browsing experience.
