several sites along with gmail fails with SEC_ERROR_UNKNOWN_ISSUER
Renowned sites with those like Gmail is getting blocked out by mozilla with the error SEC_ERROR_UNKNOWN_ISSUER.
I'm sure there aren't any malware or security software injecting any certificate & still Firefox intercepts it as a false.
While I appreciate firefox alerting me of a possible threat, its too much to not provide an option to add an exception. & so I believe that there is something I'm missing.
Can somebody direct me as in how to add an exception where firefox doesn't provides an option to do so (any config file or settings) or a setting to altogether disable the function of firefox to check certificates & block them.
Thanks for any help.

There is security software like Avast and Kaspersky and BitDefender and ESET that intercepts secure connections and sends their own certificate or that incorporates special web shielding features that can block content.
If you can't inspect the certificate via Advanced (I Understand the Risks) then try this:
Open the "Add Security Exception" window by pasting this chrome URL in the Firefox location/address bar and check the certificate:
- chrome://pippki/content/exceptionDialog.xul
In the location field of this window type or paste the URL of the website with the https:// protocol prefix (https://xxx.xxx).
- retrieve the certificate via the "Get certificate" button
- click the "View..." button to inspect the certificate in the Certificate Viewer
You can inspect details like the issuer and the certificate chain in the Details tab of the Certificate Viewer. Check who is the issuer of the certificate. If necessary then please attach a screenshot that shows the Certificate Viewer with the issuer.
Thats didn't helped cor-el. When I click on "Get Certificate", it just says "No Information Available"
Meanwhile I'm coming across another issue. At this particular site which happens to be a pretty renowned one, Firefox says the following Secure Connection Failed The connection to the server was reset while the page was loading.
The page you are trying to view cannot be shown because the authenticity of the received data could not be verified. Please contact the website owners to inform them of this problem.
Any known workaround anyone ??
BTW I loved firefox & used it for last several years. But lately, Firefox playing the BigBrother with https sites is an absolute mess. From a user's perspective I would say , the policy should be "Warn & Step Aside". If not then, no matter how much I hate it, I'll have to eventually move away from firefox.
hello, can you give us more information about the error on gmail by clicking on the error code, copying the text to the clipboard and then pasting it here into a reply in the forum.
thank you!
Hi Philipp,
Please see attached the error that I'm getting for Gmail.com. I attached the screen shot from another website as well. Just in case that helps setting up a concurrence.
Thanks

This Connection is Untrusted is sometimes caused because the computer system clock is wrong. Check the time / date / time zone settings.

I tried this already & posted the result after the first time you advised.
Who is the issuer of the untrusted certificate?
Can you post a screenshot that shows these details?
