Somehow, I was logged out of my Firefox account on my PC laptop. Because I forgot my password, I went through the process of changing it. I received a confirmation from Mozilla, saying that I had correctly changed the password, but when I try to sign in, it says that the password is wrong. I tried several times with no success. Because I never did anything with my Android phone, I am able to access my Firefox there. I have no idea what to do next.
