Google.com gives me this error:

The owner of www.google.com has configured their website improperly. To protect your information from being stolen, Firefox has not connected to this website.

This site uses HTTP Strict Transport Security (HSTS) to specify that Firefox may only connect to it securely. As a result, it is not possible to add an exception for this certificate.

Can't Add Security Exception in Advanced for some bullshit reason that I don't know and when I do click Advanced, this is what it gives me: https://www.google.com/

The certificate is not trusted because it is self-signed.

HTTP Strict Transport Security: false HTTP Public Key Pinning: true

Hi, lordsaurfang. Sorry to hear that you're facing issues using Firefox. The symptoms you're describing sometimes happen if your device clock is not working properly. So

  1. First check your date and time
  2. Restart your device and try again.
  3. Also if you can check with your Internet Service Provider see if they know anything about that

If the problem is still there then let us know.

Hi lordsaurfang, you definitely should not get the

The certificate is not trusted because it is self-signed.

error for Google sites. It sounds as though something is intercepting your connection.

Since your certificate data seems incomplete, we don't have any explanation yet.

Q1: Is Google the only site affected?

Q2: I assume Firefox worked normally before. Can you think of any recent changes before this problem started, such as new software installations or updates?

Q3: Could you check your connection setting:

  • Windows: "3-bar" menu button (or Tools menu) > Options
  • Mac: "3-bar" menu button (or Firefox menu) > Preferences
  • Linux: "3-bar" menu button (or Edit menu) > Preferences
  • Any system: type or paste about:preferences into the address bar and press Enter/Return to load it

In the search box at the top of the page, type proxy and Firefox should filter to the "Settings" button, which you can click.

The default of "Use system proxy settings" piggybacks on your Windows/IE "LAN" setting. "Auto-detect" can lead to a flaky connection. You may want to try "No proxy".

Any difference?

A1: Yes, it's only Google. Although the sites associated with Google like GDrive, Gmail and GDocs have minor problems like annoying slowness, missing pictures and logos, as well as a broken UI.

A2: I always keep my Firefox updated to the latest version. I only use CCleaner as my clean-up tool and it erases some data like my history on Firefox for me.

A3: My proxy has always been set to "No proxy." Never changed it.
