Had a this appear after a connect request sent from a legitimate email from linkedin in my yahoo email.

I guess "Action Not Found" page with "For request 'GET /' " message

When I clicked on the request I received the above message. When I try the same address in Chrome it said the server couldn't prove it was linkedin.com; its security certificate was from *innovid.com. This may be caused by a misconfiguration or an attacker intercepting your connection

I get it (linkedin) as verified by DigiCert Inc

It is quite possible the link in the email is not quite what it appears.

So you have a genuine problem with the wrong site; or something is interfering. It is important you work out whether it is one (or a very limited number of sites) or whether it is all secure sites, that Firefox does not like.

This forum website is also verified by DgiCert

  • Do you get a green padlock and a circle with an i in it?
    Put the mouse pointer to that then click it. What do you see ?
  • See also screenshots in Site Information panel

If it is not a dodgy email link then hopefully it is some annoying security software interfering and you will need to change its settings or something as explained in this article which lists specific solutions

Please post back to say what you find & how you get on.

John99:

I tried https://linkedin.com and get the same screen and message. When I hover my pointer over the "i" it says I have added a security exception to this site. When I click on it, it states by the green lock "secured connection" and under "Permissions" - "you have not granted this site any special permissions". Now on my smartphone it won't let me sign on. Only on my vpn through work am I able to access the site.

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.
