I am using headers, form to try and log into a web form. However the sites bot protection is showing the user agent as python and rejecting it..

headers:
User-Agent: "Mozilla/5.0 (Windows NT 10.0; WOW64; rv:42.0) Gecko/20100101 Firefox/42.0"

Agent detected by the site (I am admin and can see the logs):

AGENT: Python-urllib%2F2.7

It appears that the form plugin is the one that is not sending the new user agent.

I saw an old ticket indicating that using the default Python agent was a bad idea, and I agree. The program should probably ID as flexget + build number.
