Sorry, I'm out. My browser is my agent. I don't want it to analyse my browsing data and send the resultant classification to random machines over the internet. Why is this even a thing? Browser's job is to display websites, not spy on the user.
If advertisers want to track me, they can create their own software and entice me to install it. Oh wait, that's exactly what Google did with Chrome :(
