We tried several times to log in to chase.com and repeatedly received this message:

****************************************************************************

Network Protocol Error [large letters]

An error occurred during a connection to secure09ea.chase.com.

The page you are trying to view cannot be shown because an error in the network protocol was detected.

   Please contact the website owners to inform them of this problem.
****************************************************************************

This is unacceptable. We do not want to use insecure browsers, and the Chase website was fine until the latest Firefox update.

Could be a problem with HTTP3. You can try to disable HTTP3 to test to see if that has effect.
