Actualy I reinstalled Burpsuite with the newest version I think 17.03.What heppend now is that I recieve this error on the browser: The owner of www.google.bg has configured their website improperly. To protect your information from being stolen, Firefox has not connected to this website. This site uses HTTP Strict Transport Security (HSTS) to specify that Firefox only connect to it securely. As a result, it is not possible to add an exception for this certificate. Learn more… www.google.bg uses an invalid security certificate. The certificate is not trusted because the issuer certificate is unknown. The server might not be sending the appropriate intermediate certificates. An additional root certificate may need to be imported. Error code: SEC_ERROR_UNKNOWN_ISSUER And on the burp I recieve this : GET / HTTP/1.1 Host: abv.bg User-Agent: Mozilla/5.0 (X11; Linux x86_64; rv:45.0) Gecko/20100101 Firefox/45.0 Accept: text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8 Accept-Language: en-US,en;q=0.5 Accept-Encoding: gzip, deflate Connection: close

You need to install Burp's CA certificate in your browser to get rid of SSL / HSTS errors. Instructions are here: https://support.portswigger.net/customer/en/portal/articles/1783075-installing-burp-s-ca-certificate-in-your-browser

Is this affecting all sites or only some? What error messages do you see when the connection fails, and where do they appear?

I installed Burp's CA certificate in my browser, following those instructions. I then restarted Firefox. I am receiving the same error.

Neo - are you saying that when you have Proxy interception turned on, then requests made by the browser don't complete? This is expected behavior. You need to click "forward" to send each intercepted message on to the server/client.
