Using Firefox as my default browser
Since last Friday I haven't been able to access any of my bank accounts with US Bank. I can access these accounts through my US Bank phone app and through Chrome when I use it on my laptop as browser. When I called US Bank IT they could not help because the phone app and Chrome worked. What's happening with Firefox? I have used it for years to get to these accounts, and now I am unable to.
I'm guessing here, but actually a lot of banks seem to be affected, so:
Firefox recently rolled out "Total Cookie Protection" to more users. This limits how sites can use "third party" cookies, meaning cookies from different websites than the one you see in the address bar. If you notice that there is a different address in the address bar between the main bank server and the sign-in page, or between the sign-in page and the online banking area, then this cookie restriction could break the connection.
You can make exceptions to this feature when needed. More info in the following articles:
