Coming from other browsers - LastPass just worked. However, i'm trying to make the jump from Chrome to Firefox (As many are, with Google continually taking the "Don't" part out of its motto) but this constantly broken functionality is a mess. Blank or no popups, trouble detecting if there are fields to fill in, no version options visible. At this point I'm keeping a separate browser up just to get to my passwords.

Issues:
1. NEVER accepts login from toolbar or variations such as accepting to enter email but refusing to take passwd.
2. Inconsistency in saving auto-generated passwds. You generate a passwd and can't login since it's not been saved.
3. Maybe related to no.2 ...once in a while an entry is created but multiple times. Occurs even when editing sites and notes.

##Update 26/01/2019
Have been using the signing function for ~ 2 weeks now. Wohoo!!!! Now for those duplicates to be resolved and for lastpass to remember a password when I am signing up more consistently.

Ubuntu 18.04.1
Version 64 Mozilla Firefox for Canonical - 1.0

whenever i use lastpass password generation tool to change my passwords, it doesn't ask for password update, i got locked out of a website's account because of this, it helps you generate a password that you can't remember and then doesn't save it for you, this sucks

Lastpass has saved me from password resets multiple times per day for the past several years. I rely on this add-on and the chrome add-on for carrying out daily business, safely sharing sensitive passwords with people, and more. This add-on is great and I almost never have problems with it.

This extension works well, after you login either through lastpass.com or its moz-extension page, but never through the toolbar shortcut. It's a small annoyance that I'd loved to be fixed, LogMeIn.

Muy útil y el precio me parece muy accesible.

With over 350 (nearly all unique) passwords, this gives me an additional layer of security, and I can access them from any device/location, and don't need to remember them. No worries about someone figuring 2 or 3 re-used passwords out and then having access to my whole life, or writing them down on/in something that can be lost, stolen, or damaged/destroyed. I can use it from any browser or as an app on my phone, and so can the rest of my family. All we need is to know the Lastpass password and the one for the primary email account. A God-send!

lastpass, over the past two updates has not been syncing across my laptop and my smartphone. it has me listed with two accounts a change I did not make but failed to notice for a time, and I am forced to try to utilize the stored passwords from the separate accounts. And for this fubar, they make me pay?

Mostly positive experience. Convenient for using on multiple devices. No issues with security
