After lunch, I started Firefox, but it was unresponsive with a blank tab with no effect to manually putting in a website. Went to Mozilla site and downloaded newest version of Firefox (50.0). Still no response. I did not reboot my computer after installation because that was not indicated.

Some problems occur when your Internet security program was set to trust the previous version of Firefox, but no longer recognizes your updated version as trusted. Now how to fix the problem: To allow Firefox to connect to the Internet again;

  • Make sure your Internet security software is up-to-date (i.e. you are running the latest version).
  • Remove Firefox from your program's list of trusted or recognized programs. For detailed instructions, see
