Hello.
I have a Bitwarden account and can login normally.
But I tried the Firefox addon (with latest FF release) and It simply does not work : saying wrong email or password.
My Bitwarden account is empty (no password registered inside).
Hello @Parigot-Manchot - welcome to the Bitwarden community forums.
That is very strange - the FF add-on works for me on MacOS, Windows, and Linux.
Are you able to login successfully at https://vault.bitwarden.com? Or are you self-hosting your server?
I can log without any problem.
Ok just tested in Chrome, and it worked 
Will try to clean my Firefox installation…
