Exported certificate mismatch with this from proxy connection

Hi, I regenerate certificate on burp, restart it, export from burp, import to firefox and passing requests thru burp then I have "MOZILLA_PKIX_ERROR_MITM_DETECTED" where after checking serial number and SHA1 between both certificates (this one from "check certificate" when error occured and this one imported previously) I can see that they are different! What is happening? Im on Windows 10, working on firefox with ProxyFoxy addon. Burp Suite Proffesional v2.1.03

Hi, have you tried accessing this website without ProxyFoxy? it might be interfering and causing this exception.

Hey! It is happening at every page, of course I tried with and without proxy configuration. Whenever I turn off foxyproxy - all back to normal.

Mike Eaton - you have right! Now I get it! Now I'm able to run sites thru burp suite without foxyproxy addon but with strictly configured proxy options inside firefox and it work like a charm! Thank you!
