Saves passwords, works well.

This version of the extension doesn't have 'copy username' or 'copy password' options like its chrome counterpart. :( I like the new firefox and am growing annoyed at the omission on lastpass' part.

Super useful.

he dont do autofill passwords and user names of local devices i must copy past it manuly

Perfect

not working properly on firefox quantum ... it logs off every time a restart the browser .. really annoying

Gets confused sometimes

Does not work well with websites that use Web Components polyfill, for example https://polymer-project.org/ or https://cloudstitch.com/.

I reported this to LastPass more than 2 months ago and it is still not fixed.

LastPass is always great, but the Add-On for Quantum really sucks.
It forgets the mail, and it happens that, even though I'm logged in, it does not load my accounts (list completely empty)

This plugin lacks a couple key features compared to other browser versions. The most important one being the ability to copy a password or user name without having to open the full application and "un-hide" the password.
