 I have just reported a flaw with passing a misconfigured ssl/tls
 certificate which is allowing MITM. I reported that against https-
 everywhere but they answered it that https-everywhere doesnt access ssl
 info. So maybe it is a browser level issue?

 otherwise really what is the use of green lock and https-everywhere plugin
 if a website pretend to be having ssl/tls connection while in fact its
 just fake one and MITM is possible through it ?
