Sites Web regularly not approved since refreshing Firefox. I deleted cert8.db; time settings are fine, but still does not work. What should do?

First had error message saying that something prevents update with the Firefox Firefox refresh query. So I did. Result is common Web sites such as google and own sites of mozilla not opening not because "Untrusted connection" - (error code: sec_error_unknown_issuer).
I am working on Mac OS X 10.10.2
Has deleted the cert8.db in folder profile a couple of times, but does not work.
Time settings are fine.
Removed the whole browser app and reinstalled again; same problem occurring. What is going on? And above all, how can it be fixed?

Ah, you see AVAST there under the issuer of certificate?

Your Avast security software is intercepting your navigation to filter threats. In order to filter connections secure, Avast creates these false certificates and presents them to your browser. Since Firefox uses a certificate from Safari, Firefox should be set up to trust in Avast to generate these certificates.

Now... in theory, Avast is supposed to update Firefox automatically when you go outside and start it again. I guess you left Firefox since this problem started, but, if not, that give a try.

If this does not work, you or a volunteer will have to search the steps to get the Avast signing certificate in Firefox.

Plan C would be to get the old file cert8.db file old data of Firefox on your desktop and it transplanted into your current Firefox profile. You must already have been put in place to work with Avast.
