I'm working on a project that uses WWW::Mechanize::Firefox to visit a website and download a file. I want to access the web site using a different IP. In WWW::Mechanize, I can use local_address method to assign an IP to the mechanize object. However, WWW::Mechanize::Firefox seems not allowing me to use local_address. Are there any alternative methods to assign an IP to an object of WWW::Mechanize::Firefox?
