I have used this addon by years and saw no problem. Two factor auth. works perfectly.
Yıllardır kullanırım, hiç bir sorununu görmedim. İki aşamalı doğrulaması ise takdire şayan çalışıyor.

I actually really love LastPass and I would LOVE to have it as an add on on my browser but I've added it a dozen times over the last few months and it keeps disappearing and being disabled. Today I added it four times only to have it IMMEDIATELY disappear. It would be really nice if I could actually use your service.

When it works, it works great. But with every update from Firefox, the extension breaks. Very aggravating!

It is no longer possibel to auto fill forms - therefore this extension makes no sense anymore for me so I will delete it from my system

So many people complain about LastPass when it's one of the most used and secure password managers out there (just give it a search).

PS: The only thing I would recommend is a tutorial for beginners. The interface, for a beginner, is quite unclear.
