No, it is very good thing when enabled. https://support.mozilla.org/en-US/kb/firefox-protection-against-fingerprinting
Hardened firefox, arkenfox, librewolf, tor browser all have it
If you try to reduce your fingerprint, it itself creates a unique fingerpint. As you said 99% users do not use bitwarden, the same way 99% users do not use brave.
To reduce your fingerprint has many layers. Not using any extension itself creates a unique fingerprint. As 99% users will atleast install one extension be it UBO, honey, adobe pdf reader etc. Meaning as you do not have any extension you are among the tiny minority of 1%.
It itself is a major fingerprint as said above.
It is perfectly safe from anti-fingeprinting point of view to use Bitwarden as an extension via below point 1.). Official brave privacy team will also recommend the same.
