The additional form fields and the master login fields overwrite each other sometimes. For example, say you add the extra question answers to your lastpass vault entry for your bank login. When you come back later, your password has been replaced by the name of your second pet, or some street you lived on. When this happens, the password that got replaced is not recorded in password history.

If you must use the Lastpass extension, beware the wrench icon under 'Advanced Settings'. It might just lock you out of your bank if you use it.

Works as advertised except one: I have 2FA activated and I am infuriated by constant re-authorization prompts, despite ticking to remember the browser. I am nagged at least once a day on all my browsers.

I rarely can log in once I log out of LastPass. I'm considering other password managers for Firefox but I have too many accounts with Lastpass to desert it quickly.

Приемлимо

Absolutely less than 0 service. None of the recovery options work.

Apparently they consider Firefox a second class browser - the extension has numerous pretty essential bugs that are not being fixed for ages: copying password from the menu broke years ago, password database export doesn't work, on Firefox for android you can't even log in anymore, etc.

Straight forward and easy to use password manager.
