Another issue with Firefox is that if you have the following Firefox Options checked:
located in Tools / Options / Security:
1) Block Reported Attack Sites
2) Block Reported Web Forgeries
Then every website you visit is transmitted to Google for a comparison of what is on their block lists.
Chrome has its issues too. It sends two extra pieces of data “machineid” and “userid” back to Google.
