Have started using today. While password generation is consistently doable not like the Firefox built-in, theres way too many disgusting inconveniences, such as:
1: When updating password and the old one is required, it overwrites either the old or new one, so I have to copy/paste either one
2: (Particularly) when deleting password a confirmation pop-up always appears, though its not a permanent deletion (it only sends to Trash folder)
3: When re-generating password by pressing the recycle button, the method pop-up always appears though its already set (Takes extra time for 0 reason)
4: Shows passwords in Trash folder as an autofill option
5: Cant hover folders
6: When trying to edit passwords, I have to press twice: View then Edit. Bothering

Literally overrated. Looking for replacement

Update: After using a few days I began to feel like its not that bad. Customizable password generation and being able to use folders (Firefox cant) is at least neat.

L'extension est globalement bien, et on a tout un panel de paramètres très sympa. Il y a cependant une grosse fuite de mémoire soit sur les requêtes XHR, soit sur les liens affichés.
La RAM sollicitée est monté à 21Go chez moi et d'autres collègues sur un même tableau avec des centaines de liens et de requêtes XHR en arrière plan.
Sans l'extension, pas de problème de RAM

This is a game-changer!

Amazing

Best password manager made, ever!

Easy to use, brings lots of convenience.

Its good if you pay for it, reports function is very handy.

Actual password autofill function is far behind firefoxes own manager.

cant detect extension logins, so wont save, and wont autofill etc

Great app! I use it in Firefox-based browsers, Chrome-based browsers, macOS, Windows, and Linux, and it works great everywhere. Good support for biometry auth (so you don't need to be typing your long password all the time), and the autofill works decently (not perfectly, tho).

The best in the World

Excellent addon, but with a number of quirks and auto-fill bugs, compared to the native Firefox password fill-in: Bitwarden does not seem to detect all the places it should add credentials, or add credentials whereas it shouldn't. Also fonts and UI design is not that great: credential proposal is with huge text, obscuring other fields of the screen, something critical on mobile/small screen space (open bug for the purpose, but nothing happens); but there does not seem to be intention of fixing this at the moment (open bug for a couple of years).

Had Firefox sync handling my passwords and switched to bitwarden due to the low security ... which was resolved after many years a couple of days after switching to bitwarden, see Bugzilla #1320222 :D

Still bitwarden has a good feature set, mass password handling via the vault (ie select multiple passwords) etc. Recommended
