I can't open aol, nor can I search on google without being told whatever site it is has no license.
When I sign into aol, I get the "Problem loading page" screen. No certificate or something. When I try to use Google to search, the sites I want to visit all say the same thing.

Hi Peetdafeet, in order to connect to HTTPS addresses -- secure connections -- Firefox needs to verify that the certificate presented by the site is valid. It sounds as though there is a general problem in your Firefox with that process.
The most common reason for that these days is that your security software is intercepting your web connections and Firefox doesn't trust the fake certificates created by that software. Could you try the steps in this article for the first level of troubleshooting:

Any progress so far?
You can check if there is more detail available about the issuer of the certificate.
- click the "Advanced" button show more details
- click the blue error text (SEC_ERROR_UNKNOWN_ISSUER) to show the certificate chain
- click "Copy text to clipboard" and paste the base64 certificate chain text in a reply
If clicking the blue error text doesn't provide the certificate chain then try these steps to inspect the certificate.
- open the Servers tab in the Certificate Manager
- Options/Preferences -> Privacy & Security
Certificates: View Certificates -> Servers: "Add Exception"
- Options/Preferences -> Privacy & Security
- paste the URL of the website (https://xxx.xxx) in it's Location field
Let Firefox retrieve the certificate -> "Get Certificate"
- click the "View" button and inspect the certificate
You can find detail like the issuer of the certificate and intermediate certificates in the Details tab.
