Since no on here has access to your account you need to yourself verify that the recovery email and PINs or what other part of that settings is correct otherwise no one here can help if you lock yourself out.

Oomfie that is not what I'm saying.

I have literally generated this supposed key to recover, I hit the copy button ON the key itself, and then when trying to USE the key Firefox just says "invalid key"

So its telling me the very thing it is generating, that I am literally copy pasting is failing.

What I'm saying is, mozilla is shitting their pants.

Those were your words and opinion about them shi$%% their pants. So if you do want help ask for help but if this is just rants then no one will really help here.
