In the last week or so I am not able to log onto many of the websites I regularly use, including Mozilla sites. Each time this window I have copied below comes up. Can you tell me what to do. It is fine with Chrome and Explorer but I want to use Firefox but at the moment can't. Please help.

uninstall Firefox. Then Delete the Mozilla Firefox Folders in C:\Program Files and C:\Program Files(x86) Then restart system. Then run Windows Disk Cleanup. (Note: this should be run weekly, if never done below before will be 10's if gigs) Then run it again and click the button that says Cleanup System Files. Note: your Firefox Profile is saved. But you should make a back up before you do : https://support.mozilla.org/en-US/kb/back-and-restore-information-firefox-profiles

Reinstall with Current Release Firefox 57.0.2 with a Full Version Installer https://www.mozilla.org/firefox/all/

There is security software like Avast, Kaspersky, BitDefender and ESET that intercept secure connections and send their own certificate.

  • uses an invalid security certificate SSL_ERROR_BAD_CERT_DOMAIN
  • configured their website improperly
