Steps to replicate the issue? Without this other with lastpass Addon won't be able to replicate what your if any problems there are.

Have you contacted LastPass support?

My issue is with logging into LastPass in Federated mode. After Okta login/authentication, firefox has blank screen. this is both with Website and using Extension. Firefox 102 worked fine. Version 103.2 is where the issue appeared. I can revert back to 102 and LastPass works. Unfortunately, I cannot stop the automatic upgrade.

I am using Edge browser until this is fixed, or I become comfortable with Edge.
