How I can use this proxy in my web browser (Firefox)?

I'm trying to search Google using the "inurl:" The syntax, but for some reason Google has left me after a couple of searches because apparently the way to look mimmicks a type of virus. I have tried of different powers (including the Tor) in vain, however the problem is solved when using the proxy here: http://snoopstopper.com/ I do not want to go through this site web, whenever, however. Is there any way I can avoid this connection to this power directly through Firefox? Thank you very much
