Member of LastPass for years but lately, in 2022, after I log in frequently, the password to opened address does not automatically populate.

How do you expect me to make an assessment on your paypal, when you are preventing me from joinig up.

First encourage me to joinup and see what your service is like, before I can make any assesment of the quality of LastPass.

Very dificult

Alles super. Aber wie kommt das neue Passwort in Last Pass?

It does the basic job, but is pretty buggy. Auto-fill often failed, recently it stopped working at all. When auto-fill works, it cannot distinguish among subdomains. In Secure Notes, attachments in ZIP format are often broken, so it losses my data. I learnt that hard way.
I am using Teams plan. Admin console and shared folders are also annoyingly buggy, showing "unknown errors" often.
I am using another password manager (Bitwarden) in parallel and it is way better.

LastPass extension does not work In Firefox (Windows 10): installation stalls, and even if the plugin icon appears, it can not be used, clicking that icon does nothing (a thin line below it appears), even removing extension stalls and does not properly get removed.

This app has been my go to for years.
