Start Firefox in Safe Mode {web link}

A small dialog should appear. Click Start In Safe Mode (not Refresh). Is the problem still there?

You appear to be using Kaspersky Total Security software and Kaspersky software has been mentioned fors causing this issue with the Chase website.

I had this identical problem about a month ago - at that time the problem was CLEARLY caused by my Kaspersky security software. I contacted them at that time - they figured it out and gave me a "fix" to their software - and it completely solved the problem at that time. Problem then reoccurred a few days ago - FIRST thing I did was completely disable Kaspersky protections and try logging into Chase.com again - this time the problem did NOT go away. I went so far as to disable Kaspersky, close Firefox, restate the computer, open Firefox in "safe" mode and try logging into chase.com again - problem continues to persist. So I'm thinking the problem probably is not Kaspersky this time - trouble is, I still don't know what's causing it.

It is usually quite hard to disable security software and some components may still be active and run in the background.

Did you try to boot the computer in Windows Safe Mode with network support ?
