Firefox rejects google as a "your connection is not secure"?
Since upgrading to firefox 50.0.1 I cannot do a search with Google (or any other engine) search. I get "Your connection is not secure". Everything works with Chrome and Safari. I have a MACBook Pro OSX 10.12.1 with no antivirus. Firefox is set up to ignore IVP6 and I have no proxy. I can't even run the "SSL Labs' test page" as suggested by the Mozilla help pages. What is going on? What is stopping searches. I can browse other pages without a problem. thanks for any help.

Hi robsj, the certificate issuer is listed as "Adguard Personal CA". So I assume you use Adguard. Try:

What's your computer system and Firefox version?
Start Firefox in Safe Mode {web Link} by holding down the <Shift>
(Mac=Options) key, and then starting Firefox.
A small dialog should appear. Click Start In Safe Mode (not Refresh).
Is the problem still there?
Thanks - I tried that - did not work Computer MACBook Pro OSX 10.12.1 with no antivirus Firefox - 50.0.1 here is the entire quote I get from the error screen
"The owner of search.yahoo.com 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 may only connect to it securely. As a result, it is not possible to add an exception for this certificate."

There could be a probleem with the site itself.
Have you tried; https://www.yahoo.com/
Hi robsj, can you find an "Advanced" button on that error page? If so, please click that to find more technical details about the error. Often you'll see a blue code that matches this article:
How to troubleshoot security error codes on secure websites
But there are several other possible error codes so it's best if you can find one and let us know what you're getting.
In some cases, clicking the code will open a further panel with an encoded version of the certificate that Firefox is objecting to. You can copy/paste that into a reply for analysis. What I do with that is paste it into one of these sites to inspect the certificate details to see whether that flags up the problem:
If you end up doing the decoding yourself, could you report back on anything you learn?
I pressed the wrong button!! This did not provide the solution to the problem This ONLY occurs with 'all' of the search engines - it appears that all other sites are ok.
here is what came up on the advanced button. I checked on the decoder site, but i confess it meant nothing to me. Here is the text
search.yahoo.com 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
this is the certificate text

thanks to everyone who took the time to help me - it is greatly appreciated! I was indeed using adguard and forgot that it was active.
