Great add-on and works most of the time. I use it constantly and only ever have some issues with lag. Autofill usually works but sometimes either the URL or password field is not detected properly. Developers finally added the copy password and username features that were missing as well! Hope to see more updates to improve stability in the future.

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

Accuraat en vooral compleet programma als je tenminste de premium versie gebruikt.

This addon generally works well, but as of Firefox 63.0, the login component of the addon is completely broken. You have to login via the LastPass homepage. firefox have a problem since firefox quatum have arrive a lot of add-ons not working ok bring the old firerfox back i used it since 2004 (14 years) as my only browser
