I use the county assessor page on a monthly basis to get information on properties we are buying. At some point something changed and I get a "Connection is Not Secure" and it will no longer open that page. I can open it on another computer in the office. Not sure how to reset settings. I have uninstalled firefox and reinstalled it, but that did not help. I have Avast Antivirus, but never customized anything. web site is: http://gisapp.adcogov.org/quicksearch/. Where do I even begin to look to undo what is happening here?

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

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

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 open the about:config page via the location/address bar. You can accept the warning and click "I'll be careful" to continue.

I either am not understanding the exact steps to the above suggestions or none are working. Once the page is done running the spiral of death I get this warning..."Warning. Request Blocked.This request was blocked because a security violation was detected." Page tab title turns to "Security Violation".

Can you attach a screenshot?

Start Firefox in Safe Mode to check if one of the extensions ("3-bar" menu button or Tools -> Add-ons -> Extensions) or if hardware acceleration is causing the problem.

  • switch to the DEFAULT theme: "3-bar" menu button or Tools -> Add-ons -> Appearance
  • do NOT click the "Refresh Firefox" button on the Safe Mode start window
