i've been using this for years. the hardest part is remembering your password to get into it ! Just kidding .

This extension DOES NOT WORK ON FIREFOX. Period. It hasn't since February of 2018, and it is getting worse. In addition to a glitch logging in with the master password (clicking on the icon on the toolbar just shows an empty rectangle; you have to log in via their main web page), I am now unable to create new passwords ("invalid response") or perform tasks like exporting my passwords ("json error"). LastPass was bought out by another company and the product has gone downhill. Do what I'm doing and look at other alternatives.

This App is a godsend to old farts like me, never remember Passwords

I have been using Lastpass with Firefox for many years.
However, for the past year I have had nothing but problems with Lastpass not connecting when opening Firefox. Usually just disabling and re-enabling Lastpass takes care of the problem.
Now, with the lastest Firefox version, 63.0.3, Lastpass does not work at all. Uninstalling and reinstalling makes no difference.
Here is the major problem, that no one else seems to have experienced, Lastpass works flawlessly with all other browsers!!!
What does one suppose that means?

Bad server up time, offline mode non-functioning.

Poslední dobou se nelze několikrát za den příhlásit - "Při přihlašování ke službě LastPass došlo k chybě. Prosím, zkontrolujte své internetové připojení." Internet je přitom funkční.

Wow been using lastpass for a while now. The add-on they have made here is utter trash. It has been trash for a while now and makes me think either they're not bothered or they can't get it working properly in FF. As a premium member I may have to stop paying for this app if not sorted and move elsewhere.

guys make me log in NOW !!!!!!!!!!!! dont work in FF and chrome just look at this https://monosnap.com/file/IhW2UxAgqbaTmW5GeJrGH9ZxvW7QyU

Problem with logging in FF (always have to enter email...). Otherwise OK

I can't login to Lastpass, this is a very common problem for users. There is only one workaround, installing a very old version of Lastpass (but that's a security risk). Lastpass is either unwilling or unable to fix the issue. Some think it has something to do with having too many websites in your Lastpass vault. Intriguingly, Firefox appears to send data to Lastpass servers when I click Log In (seen using Wireshark), but noting happens. I have to copy my PWs from Chrome (not giving up on FF).

Are you boycotting FF ?
LastPass in FF don't update anymore my logging preferences. Always have to manually enter my email and password even I chose many times to fill them automatically. It seems LastPass doesn't care anymore...
Will look for another password manager.
