Stored passwords

I recently lost my computer in a storm. I had all kind of password stored on my Firefox browser. I had to get a new phone and have never used the my previous phone for Firefox or anything on the internet. Now that I am in the situation that I am in I did get a phone that has internet access and I desperately need to access my passwords. I have logged into Firefox under my name and email address. it's supposed to be easy just push a button here push a button there but I don't have any button that I see on my Android phone that leads me to my account information. If someone would reach out and help a feller that don't have any sense when it comes to the computer, I would be greatly appreciative
