Seriously, such a regression for FF Quantum is not acceptable. It has been months or even years old APIs were deprecated. With the current set of features, the extension is cumbersome and not useful. Where is auto fulfill and copy username/password. Having to go on the site -> EDIT -> Show password -> Select -> Copy -> Paster somewhere else, the workflow is really crazy..

The most consistent inconsistent pail of garbage one can be forced to eat out of. Just ONCE, even after re-installing and updating Firefox, would be nice if Last Pass could auto fill and log into my two email addresses. My blood pressure and gray hair plead with me to abandon this JOKE of an add on!

It stopped functioning properly some time ago. It does not log out automatically, it is not able to fill usernames and passwords, it loses newly generated passwords frequently, not able to save new sites, etc., etc. This add on is a piece of junk.

With the current bugs (constant re-authentication, no copying username/password, no auto-fill) this extension is useless for me. Due to missing Firefox 57 support of this and other addons I have kept Firefox 54 for now with all auto-updating disabled. For all those in the same boat who want to also revert the LP extension back to a working version, here's the link:

This addon do not do nothing!!
Wast of time!

Not working. Cannot login.

Не может войти в аккаунт.

I've used this for years and now can't login twice in the past week. Can login with Chrome.

Installed Firefox 57 for Android and LastPass add-on, but can not even log in to LastPass; after entering email + password I either get blank white page or a spinner that never goes away, depending on whether the sign-in page had an all white background or a photo or something.

Firefox 57 for Android. Couldn't login using this addon. No problem with LastPass apps.

LastPass does not work for me with the new Firefox update 57 Quantum - I use LastPass every day so it's either LastPass fixes the problems or a I move browser.

Not very user friendly. Can't figure out where to view/alter my saved passwords and where to change/enter a master password!

Add on no longer works, it will not allow any logon. I've tried multiple times and it just sits there. This is not an issue with the password as the same username and password works with the app and the website. This has been ongoing for over a week that I know of. If this isn't sorted soon, I think it may be time to find a new password manager.

TOO many incompatibility issue with the latest version of firefox

Long time user. The app for firefox 57 is not working right. It will not autofill for some of the sites I use and the removal of the ability to copy username and passwords makes it impossible to use on sites that will not autofill. I love the APP but the loss of functionality is upsetting. I hope they fix it soon. I may need to find a new password manager if not fixed. I have been going back and forth with LastPass tech support for 2 weeks nothing value. They keep telling to clear the cache which i do to no avail. LastPass in FireFox does not even let me update any passwords within my vault. Works fine with any other browser I try. Not sure why they are refusing to support the new version of FireFox. Very disappointing..

Moved from Chrome to FireFox Quantum and lost the ability to copy/see user name and passwords from "Shgw Matching Sites" dropdown.

Why is the app different between the two interfaces? Come on LastPass, you're better than that

安卓平台Firefox5.7 新版本登录不进去

Cannot copy my passwords in FF while I can in Chrome. wtf come on

Been using it for years, but recent changes to both LastPass and Firefox have brought about problems and missing functionality. To add insult to injury, my reward for being a supporter of the Premium version is having the price DOUBLED while the performance has degraded significantly.

Some users may not use features which are currently broken:

* It will not open my list of sites by clicking the LastPass icon in the browser extension in a Private Firefox window
* Attachments stored in Secure Notes will not open
* Many users report the inability to use copy & paste for usernames/passwords

24-Nov-2017 update: The binary component, used for opening secure note attachments, has been repaired, restoring this functionality. But the extension still doesn't work properly in a private browser window in Firefox Quantum.

Prompted for Multifactor Authentication all the time...

Wenn der Browser kurz geschlossen wurde, fragt die Erweiterung immer ab den Code für die Zwei-Wege-Anmeldung. Das ist so umständlich, ich kann auch wie Windows 10-App weiter nutzen.

Ever since updating to Firefox Android 57, this extension does not let me login. I have MFA enabled for my lastpass account. When I tried to login to lastpass (the extension) in firefox, it will asks me to enter the authentication code but won't let me click the "Authenticate" button.
