Hi Patricia, are you signed in as that user (19pro)? Normally, Firefox is using a profile folder ending with

.default-release

instead of just

.default

Can you see that one?

As for how to start up in a specific profile, check this article: Profile Manager - Create, remove or switch Firefox profiles - speficially the section titled "Start the Profile Manager when Firefox is closed"

Thank you, jscher2000

All the profiles I found have "default-release." How do I get the 2025 profile back into Firefox?

I will look at the article: Profile Manager - Create, remove or switch Firefox profiles and let you know. I know nothing about this so I appreciate your help! Patricia
