For some reason the screenshot did not load so here it is.

Since you use Kaspersky, a possible reason for this is Firefox not being set up to work with its feature to scan your internet traffic. For secure connections, Kaspersky has to present "fake" certificates to Firefox.

Kaspersky usually injects its signing certificate into Firefox's certificate file (cert8.db) automatically, but a Refresh removes that file. I don't know whether you can coax Kaspersky to do that again, or whether you will need to fix it manually.

I found these steps in a post on the Kaspersky forums. The actual path on disk may vary depending on your product:

Open Firefox's Certificate Manager:

"3-bar" menu button (or Tools menu) > Options > Advanced > Certificates mini-tab > View Certificates button

In the Certificate Manager dialog, click the "Authorities" mini-tab

If you see an existing "Kaspersky Anti-Virus Personal Root Certificate"

Select it and Click "Delete or Distrust"

Now click "Import..."

Proceed to "C:\ProgramData\Kaspersky Lab\AVP15.0.1\Data\Cert\"

Select "(fake)Kaspersky Anti-Virus Personal Root Certificate.cer" and Open!

Does that work on your Firefox?

I should have mentioned that there are several other possible reasons for problems with secure sites. If the above does not help, please expand the Technical Details section of the error page and look for an error code in parentheses (separated_with_underscore_characters) and paste that into a reply, since it may help identify the problem.

OK i tried to follow the above path but there is no data. I then tried going to program files and then to Kaspersky but again no data in there either nor any part of the above path could be found. I have enclosed another screenshot showing the details under technical details.

Okay, did you have to create an exception to use this site in Firefox or is the secure certificate problem limited to only Google and Yahoo?

If you created an exception for this site, please compare the certificate with the attached screen shot. You can do that by clicking the padlock (or warning triangle) in the address bar, then More Information, then View Certificate. In particular, what do you see under "Issued by" and in the Certificate Hierarchy?

Strange i replied to this but i do not see it. I tried to do a certificate under servers and i see it listed there but it still does not allow me to use google search nor is there a way to click on I understand the risks like i did with yahoo which now works fine. Here is a screenshot showing what i have done.

Are those "Kaspersky Lab ZAO" entries the ones you just created, or were those there before?

I think you would have better luck with the import strategy. If the certificate can't be found in the usual location, you could try exporting it from the Kaspersky setting or from Internet Explorer.

Maybe this old support article? http://support.kaspersky.com/us/9093#block1

I did not have to go through all those steps listed in that article but the certificate was saved and i then went to FF options and made google the search engine and all is working. Thanks a bunch for the help and i will bookmark this in case it happens again.
