Latest update (Version 4.2.3.20 updated Dec 4, 2017) restores functionality (including copy username/password) and resolves constant request for authentication upon browser close. Seems to be operating just like its Chrome counterpart now.

Great app

I'm using LastPass to store all my passwords. So I use it not only to store passwords for websites, but also for VPN, router etc. New version of extension is actualy worse. They removed possibility to copy password into clipboard or show it easily in extension itself. If you want your password, you have to find stored item and edit it. Editaion window is opened as new browser tab, so it is not very convenient.

Still doesn't work properly with FF 57. Keeps logging off when FF 57 is closed.

Doesn't seem LastPass supports Firefox Quantum on Win10. Very disappointing. I am migrating from Google products where possible. I had hoped for easy, but moving to FF may require a new PW Manager.

Very nice

I used to like lastpass a lot.
Ever since the new version of Firefox rolled out though, lastpass has been a pain with many of the settings not functioning as advertised.
The login box does not come up when I open the browser.
Many sites that I used to be able to autologin on now won't do that.
As a premium user I hope this gets addressed soon or I'll be looking for a different solution.

Doesn't seem to work or do anything

Ok

This app save me a lot of headaches.

LP lack of support for Firefox 57 is terrible. Must reenter emailAddr/PW every time.

So called new version released 1 Dec 4.2.1.21 doesn't work either.

I see several folks are switching to KeePassX and Dashlane.

What's your experience and how much trouble was it to migrate your LP data over to them?

Just checked Dashlane. They have a provision just for migrating from FF. See under "support"
