  • Hi,

    I have noticed that you are using Firefox to access google and facebook webpages. Have you tried IE to access these webpages?

    You can try these steps to deal with the issue:

    1.Clear the Cache

    Firefox/Tools > Options > Advanced > Network > Cached Web Content: "Clear Now"

    2.Remove Cookies from sites causing problems:

    Firefox/Tools > Options > Privacy > "Use custom settings for history" > Cookies: "Show Cookies"

    3.Start Firefox in Safe Mode to check if one of the extensions (Firefox/Tools > Add-ons > Extensions

    Switch to the DEFAULT theme: Firefox/Tools > Add-ons > Appearance)

    Do NOT click the Reset button on the Safe Mode start window

    4.Perform a clean boot to disable the third-party software and turn off your firewall

    5.Delete the key pin manually

    Close your web browser first. Then open the file SiteSecurityServiceState.txt in your profile directory. For example:


    For Mac users: /Users/[username]/Library/Application Support/Firefox/Profiles/[random].default

    Delete the related domain entries. Save the file and start your browser again.
