The add-on itself works great. However, there have been login related issues in the last couple of updates. IF you are using 2FA, you'll have to go to Firefox Menu > Add-ons > LastPass > Options > General > General Tab > ENABLE "Open extension pages in dialogs". Otherwise, it simply won't log in. I was frustrated by this for a month.

I have used this extension for years with absolutely no problems. I use several browsers and I use LastPass in all of them. As a Systems Administrator this extension has saved me many hours of work! I find it secure, easy to use, through, and extremely convenient.

Just don't lose ur password cuz LastPass don't have it

This is the only password manager I have ever needed since discovering it through a friend in 2016. Keep being awesome, Last Pass.
