I had the old extension (now called "desktop app ver.") and it worked just fine until I tried this one. Autofill is not working now on either the old or the new version.
Update: I read other reviews and discovered the incompatibility with DarkReader, so I solved the problem, but one question remains. What is the difference between this and the old app? Why should I download a new extension?
Response to developers: First and foremost, thank you for your prompt response. Secondly, I am not a programmer and had to research to understand what Manifest V3 is, so please forgive my ignorance. I will improve the rating because I appreciate the development efforts.

it would be 5 stars if it didn't crash the reply page of a forum i'm on

quelques soucis avec premium, mails anonymes ne fonctionne pas (idem android 14), navigation très lente (firefox/windows), suggestion de création de sous dossiers...

NordPass, without the Firefox extension needs some work; it occasionally fails to automatically ask me to add a password for a new website that I generate a password for, or keeps offering to generate a password for the website when I am typing in a password. There seems to be a conflict between Mozilla's own password storage (is that connected to Nordpass Password addon?) and Nordpass. Another issue is Nordpass has allowed me to open and pay for two separate Nordpass accounts without telling me that I already have a Nordpass account. I've been with Nordvpn a long time and it works okay when Ubuntu 22.04 Pro opens it from the CLI. But the interface to Firefox seems to have problems at times. Not sure if it because I use cookie and adblockers on Firefox. Doesn't Firefox have its own password vault? Maybe that's the source of the problem I see.

Great add on that is fast, simple and easy to use. No longer have a need for the desktop app.
