Hi, that's rich considering the warning red page comes from Google. https://support.mozilla.org/en-US/kb/how-does-phishing-and-malware-protection-work

Is this about going from a secure HTTPS page to an insecure HTTP page?

Firefox 51+ will mark HTTP connections with a padlock with a strike through and shows "Connection is Not Secure" if you click the Control Center 'i' button at the left end of the location/address bar.

Note that this message is meant as a warning that you could be vulnerable and that it shouldn't prevent (block) you from accessing the website.

You can press the ESC key to close a doorhanger with a warning message in the name and password field.

You can disable the warning that opens when you type in a name/password field by setting this pref to false.

• security.insecure_field_warning.contextual.enabled = false

You can remove the warning in the location bar by setting this pref to false on the about:config page.

• security.insecure_password.ui.enabled = false

Trying to purchase a buy-it-now item from Ebay and as soon as I click on the BIN button I get a warning this site is dangerous and someone may try to steal your information.

What's the URL of that page? You don't have to include the item information, you can delete everything after the "?" when posting the address.
