Is there any Firefox plugin that allows to change how Firefox perform name resolution? I want to override the system-wide hostname resolver to attach some IP to certain hostnames.
Let me explain. Let's say I'm developing a new website and I want to test using the actual hostname but my site is run by a local webserver, I'd like to do this:
System-wide resolver: www.domain.com ---> 10.20.30.40 Ovveride by addon: www.domain.com ---> 127.0.0.1
Is there anything like this? Thank you.
