As soon as you visit a website someone is likely trying to track you for the purposes of analytics, determining your browsing habits to target adverts at you, etc, etc
If that's a major concern to you then I wouldn't recommend using any of the major browsers as none of them are particularly good at stopping all forms of tracking (this isn't the same as being insecure though as this sort of tracking doesn't use vulnerabilities in your browser, but things like cookies, etc).
Personally, I try not to worry too much about advertising companies tracking me, but If you're wanting a browser that's more careful with your privacy, have a read of this:
