i like it very much.

add Ukrainian and Russian in this add-on

Easy and intuitive to use. Sometimes autofill doesn't work which admittedly is sometimes me not having my entries set up correctly. Worst-case I need to click on the icon in the top right and manually copy/paste credentials. That's nothing for someone used to using a desktop password manager like KeyPass.
Never had any major issues with LasPass but for the love of god dont lose your master password. Learned that the hard way and had to start over.

Last Pass is essential for me. I could not manage all my passwords without it.; life online would be dangerous or impossibly complex

Très bonne extension. Avec la nouvelle version de Firefox 77, tout remarche bien.
