Hello,

I would like to know why all of a sudden video clips, some web sites and my online banking I get "did not connect" Security Issues, or expired certificates. I don't have these issues on any of my other browsers. I am inclined to believe they don't exist. I can log into my online banking but the page with my account data is blank.

Are you possibly using a VPN or proxy?

You can check the connection settings.

  • Options/Preferences -> General -> Network: Connection -> Settings

If you do not need to use a proxy to connect to internet then try to select "No Proxy" if "Use the system proxy settings" or one of the others do not work properly.

See "Firefox connection settings":
