What do the security warning codes mean

I am unable to provide the link u asked for. The problem occurs after I sign in and provide a password. Then the Brighthouse system sends a 4 digit code to my email. When I enter the code, I get error. Thanks for responding

Deleted all cookies, followed all the steps provided. No Joy. Remember this problem came with the new version of Firefox. Cleared history. Reloaded computer. Happens on all my computers. Is this a security issue? Could it be that Brighthouse is not following proper protocol. Works with Chrome and Edge.

Have you contacted their support?

Start your Computer in safe mode with network support. Then start Firefox. Try Secure websites. Is the problem still there?

Starting Any Computer In Safe Mode (web link) Free Online Encyclopedia

If the problem goes away with the computer in Safe Mode, the problem is with one of the other programs on the system.

As a test, disable your protection programs.

Could not get my computers into safe mode. Will try tomorrow with my computer guy at staples. Directions say press F8 until window come up, windows do not come up, only the Lenovo logo comes up, but holding F8 does not work.

Windows automatically boots up in this mode if it detects that the previous session was not shut down properly. To purposely start up in Safe Mode in Windows XP and 7, press F8 after turning the computer on and before Windows starts.

In Windows 8.1 and 10, hold Shift down while clicking Restart.

But I ended up using msconfig.

When I hold the shift key down during restart I get the following. Continue Exit and continue with windows not if safe mode Use a device Trouble shoot Turn off computer

I have another financial institution that does not work with Firefox Navy Credit Union. I will go to staples to determine how to get to safe mode.

Boot the computer in Windows Safe Mode with network support to see if that has effect.
