Ok, I tried playing with the default.action for privoxy, but I STILL cannot mask my user agent! I think I'm doing it wrongly, but it seemed pretty straight forward, so I'm not sure what I'm doing wrong.

Can someone please help and let me know what and WHERE to enter the

+hide-user-agent{the_useragent_string_you_want}

I entered

+hide-user-agent{Mozilla/5.0}

at the end of the file for mine, but it doesn't work. I also tried

{+hide-user-agent{the_useragent_string_you_want}}

No go as well.
