Why is my ip calculated more easily with anonymization plugins enabled?

Question

Domain Name System

Good time, I noticed an interesting thing, with the proxy turned on in firgate on the 2ip.ru website, calculating my ip becomes many times easier if, before turning it on, it immediately showed my ip and the leak was only from DNS.
I also tried babylist, all the same problems
Then, when firgate is enabled, there is a leak via DNS, IP via Flash, IP belonging to a hosting provider, Difference in time zones (browser and IP), Suspicious host name, Web proxy open ports, HTTP proxy open ports
A when you turn on the add-on for Kaspersky security connection, everything is perfectly hidden, but leaks are also generated on port 80 and vpn + and VPN

Answer 1

So you answered your own question. The plug-in in the browser allows traffic through an external proxy and does not affect the flash settings and name resolution, hence the DNS and Flash leaks, in addition, proxy ports are open on the server that uses firgate and it is hosted.
When using a VPN, all traffic, incl. name resolution and Flash goes through the VPN.
