Hi deepankarg-

If Firefox can't access a secure site (one that starts with https:) you will see an error page with the heading, Secure Connection Failed and a message about the error. This article will describe some of these error messages.

Secure connection failed and Firefox did not connect

Hope that helps!

I have gone through the article. It does not address the particular error message I keep on getting.

The error is very infrequent. Once I click on the OK button, many a times, the firefox resubmit the page and it works fine. sometimes it does not.

I've removed the solved status from this thread as you still seem to have this problem.

Are you using a direct connection or a proxy?
Do you have a router or security software (firewall) that might cause this problem?
Do you have problems with other secure https connections?

You can see the connection settings here:

  • Tools > Options > Advanced : Network : Connection > Settings

See "Firefox connection settings":


From another post by you:

refreshing the network card parameters seems to have solved the problem.

But again the problem has resurfaced and I am getting frequent error
" SSL received a record with an incorrect Message Authentication Code.

(Error code: ssl_error_bad_mac_read) "

It is becoming very irritating since it is preventing me to access most of the https site including gmail. The most frustrating part is that the occurrence is not predictable. When the error comes and I click ok, the page is resubmitted and many of the times the page is loaded properly. The problem again occurs when I want to proceed to the next page.
