So far I'm having a good experience with the Nord Pass extension aka add on. I haven't had any problems so far. I like that it also will update any information as needed in the vault. I'm happy with it so far.

Perfectible but good enough to keep. It should, by default, offer to clear Firefox's saved password database (or import/merge it).
Too many "false positives" when updating information - something changed in a field, fine, but which one? And why can’t I ignore updates on a given page?
The "new password" prompt is annoying: I have a better generator, but it's impossible to disable this one.
If there’s an option to automatically check "Stay logged in" boxes, it’s nowhere to be found. Not to mention websites that show a login prompt even when you're already logged in...
The handling of shared passwords is pretty poor - for example, professional sites with LDAP-based authentication, all using the same password.
LDAP connections should have their own category, with each site able to allow (depending on the case) login by username, email, or domain\username, always using the same password, of course.
Ideally, it should include an Authenticator feature to enable complete login without requiring a third-party tool: passkeys aren’t universally supported or always reliable.
There should be an option to manage API passwords for certain sites, storing a reusable copy as needed.

There's definitely room for improvement, especially on the mobile side. Coaxing the app to fill passwords can sometimes be a chore (mobile), and the fact that on desktop, the passwords can be hidden by the browser prompt (should you be using that as a backup) can overlay NordPass' prompt. That said, the interface is very clean, the price is very reasonable, and I feel like they're making strides to make the product better.

Excellent Password manager with lots of progress in the last months compared to original versions. Sometimes does not work well with Firefox, but keeps improving so hope issues will be resolved soon, becausedeveloppers seem to be pretty reactive.

NordPass Vault works great but has some issues with sites that delete passwords on a schedule that the site owner controls. The auto-fill has to be defeated before creating a new password on these unique websites. Mostly Government controlled, BATF especially!

i like this extension and it's very useful and hopefully secure but i need the PC app sometimes and now it's losing support wich is a pain.
