I am unable to use Fidelity Investments using Firefox Version 134.00. Just says "Service Unavailable"

What does that mean... more detail please. Are you having issues getting to the site or is this happening after you login? Do we have to login to replicate the issue? Provide steps to replicate the issue if login is not needed. Screenshots would also be helpful.

Thank you for your response.I can sign in then it goes to a page that says "Service Unavailable" thats it.. Yes you would need to log in to see this (see pic attached). I am using a Mac with the latest update (Sequoia 15.1.1) along with Firefox 134.00. Fidelity works fine on Safari..

Thanks.
