Firefox is blocking ALL access to Wikipedia.
EVERY search I do on Google (even searching for Firefox) turns up a Wikipedia page, but when I click on it Firefox will NOT allow access, only these error messages:
"This Connection is Untrusted
You have asked Firefox to connect securely to en.wikipedia.org, but we can't confirm that your connection is secure.
Normally, when you try to connect securely, sites will present trusted identification to prove that you are going to the right place. However, this site's identity can't be verified. What Should I Do?
If you usually connect to this site without problems, this error could mean that someone is trying to impersonate the site, and you shouldn't continue.
This site uses HTTP Strict Transport Security (HSTS) to specify that Firefox only connect to it securely. As a result, it is not possible to add an exception for this certificate."
It does not allow access. I trust Wikipedia, and want to access it. Is dumping Firefox the only answer?

If you can't inspect the certificate via "I Understand the Risks" then try this:
Open this chrome URI by pasting or typing this URI in the location/address bar to open the "Add Security Exception" window and check the certificate:
- chrome://pippki/content/exceptionDialog.xul
In the location field type/paste the URL of the website
- retrieve the certificate via the "Get certificate" button
- click the "View..." button to inspect the certificate in the Certificate Viewer
Check who is the issuer of the certificate.
You can inspect more details like the certificate chain in Details tab of the Certificate Viewer.
Try to rename the cert8.db file (cert8.db.old) and delete the cert_override.txt file in the Firefox profile folder to remove intermediate certificates and exceptions that Firefox has stored.
You can use this button to go to the currently used Firefox profile folder:
- Help > Troubleshooting Information > Profile Directory: Show Folder (Linux: Open Directory; Mac: Show in Finder)
- http://kb.mozillazine.org/Profile_folder_-_Firefox
If that has helped to solve the problem then you can remove the renamed cert8.db.old file. Otherwise you can rename (or copy) the cert8.db.old file to cert8.db to restore the previously stored intermediate certificates. Firefox will automatically store intermediate certificates when you visit websites that send such a certificate.
If that didn't help then remove or rename secmod.db (secmod.db.old) as well.
Is it possible to fix this so I can access Wikipedia without having an advanced degree in computer lingo?
Or should I just stop using Firefox?
