random-agent-spoofer add-on for firefox

I am using this add on for Firefox
https://addons.mozilla.org/en-US/firefox...t-spoofer/
https://github.com/dillbyrne/random-agent-spoofer

PRO:
its great it! spoofs many browser headers! 
browser, OS ,location ,via ,x-forward-for etc 
scrambles your identifiers a treat! 
I cant find anything else that spoofs your originating ip through a proxy with random IP anywhere else, 
without crafting packets yourself.

a great addition for your browser whist internet surfing
