Suddenly I can't access certain secure websites. I get the Secure Connection Failed and that TLS mechanisms are not working, and that I need to tell the websites to upgrade. I cannot wait for these websites to decide to update I need to access them now, and I know they are legitimate. How can I bypass these warnings and access the websites.

First, check that your Date and Time are correct. Also, look at Secure connection failed and Firefox did not connect.

finally, please update to Firefox 41. Update Firefox to the latest release

Hi tinav, could you copy/paste the full explanation from the error page about the problem? Or would you be interested in posting the addresses of these sites so volunteers can compare their results? Otherwise, we could only speculate on what is causing the issue.

Also, even if you trust the sites you want to visit, what Firefox is reporting is that the certificate presented by the server does not match the site or cannot be validated, or that the server is proposing such a low level of security (weak encryption or another flaw) that Firefox cannot be sure it really is a secure connection. The best next step depends on the details of the issue.
