Starting from FF Quantum, every time I open FF I need to login again even I've chosen remember login and remember password.

Does not work. LastPass support says Firefox for Android is out of scope.
This add-on should be de-listed.

не работает.
no working
firefox 56

LastPass v4.9.0+ (including 4.9.1.1) fail to work for Waterfox, Firefox ESR, Cyberfox, Pale Moon and other Firefox forks, with no menu showing when click toolbar button, though it shows up for Firefox Nightly. Note that the Universal Installer is sometimes behind a version, as it only installs 4.7.1 (not 4.9, thankfully in my case). However, you may want to set Update to Off in Addon Manager for LastPass to prevent upgrading back to 4.9 if it doesn't work for your browser, after downgrading.
Tip: If you want Copy Password, then either A) run the Firefox Universal Installer (https://lastpass.com/misc_download2.php) (works even for Waterfox) or switch extension to 2.0 mode (using this page: https://lastpass.com/change_ver.php - not sure if 3.0 mode does too, or more likely is just to be used to revert back to 4.0 mode), or install 3.x version of extension.

This addon has been garbage for months now. Constant problems.

logoff upon closing

Isn't working with firefox since around 2 weeks ago. I tried re-installing and all I get is the grayed out icon and when I click on it a weird up arrow appears that doesn't open anything. I can use it in chrome ... but that doesn't help much since Firefox is my main browser.

Lastpass schickt mir eine Rechnung über 12 USD, wie jedes Jahr, bucht danach aber 28,56 USD ab und benachrichtigt mich dann auf Nachfrage, daß sie zwischenzeitlich Preise ein bißchen erhöht haben.

I used to LOVE LastPass. But the last year or so there have been so many problems. Having to relogin every time FF is restarted, support for basic auth removed, and the latest feat: unable to login at all, which means I am unable to access any site where I have a login.

No longer work with Firefox Android.

as " serantorino" wrote for version 56 of FF: No usage possible, because I can not log in any more (FF ESR 52.7.3 64-bit (de))

stop working 56. It draws the dialog that asks for credentials underneath the toolbars and rendering window. All you see is a tiny piece of a triangle drawn over a bit of the menu bar.

This add-on doesn't work right on Firefox ESR. It draws the dialog that asks for credentials underneath the toolbars and rendering window. All you see is a tiny piece of a triangle drawn over a bit of the menu bar.

stopped working in 59.0.2 (64-bit)

The Firefox add-on icon shows up in the browser, but when you click on it, it no longer displays a dialog. It shows just a little piece of the dialog box but does not pull down to show the window. https://imgur.com/a/QLY6a

I tried removing the add-on and re-installing several times.

Stopped working in 52.7.3 - was working fine before :( Only get a blank arrow when trying to log in.

It will not work with Firefox version 59.0.2 / Tried it again today, Firefox does not recognize the add-on!
Very frustrating.

Broken. Still broken. When are you Last Pass people going to fix this add-on. Have you any idea how frustrating it is to use your APP on my phone and tablet, but be unable to use it on Firefox for DeskTop. This is like the APP from Hell. I'd give it no stars if it were possible.

The firefox add-on is broken. It works intermittently at best and often not at all. LastPass seems to have gone downhill since the acquisition.

Please fix it. And if you are a new user, beware until fixed.

Can't log in to this with Firefox Android. Multiple problems. So I uninstalled it and now it won't reinstall at all. Junk.

Stopped working. Really poor manager--unreliable. Stay away!!

Раньше работал,сейчас значок оранжевый и не открывает пароли...!!!херня!

Every time Mozilla update their browser this year I lose LastPass and therefore all my passwords and then have nothing but trouble re-instating it. Now looking elsewhere
