can't even show login window. disaster.

LastPass has been in decline for the last year, and latest updates just take it from bad to worse.

- Latest version it is impossible to login to the extension. You must visit lastpass.com to even get the plugin to accept the login.
- Preference settings repeatedly do not save. I hope you like the defaults because you can't change them.
- Often the plugin menu itself will not even open if I need to login to a site. I have to open a new tab, then open the menu, and copy/paste the password out manually.

This extension is junk. My company standardized on LastPass about 5 years ago and it didn't suck so much then. Now I think we made a mistake and would not recommend this service to anyone.

I used to love this extension. I loved it so much that it was the only reason why I switched back from Chromium to Firefox. However since then it's becoming worse and worse. First Firefox quantum got there which made this extension utterly useless. I could understand that the developers needed time to update but it's almost 8 month now and nothing got better. It's even worse.
First the copy username/password buttons disappeared and were re-added last week. However they still does not work !!!
The autofilll is now way worse and does not fill anything or use wrong credentials.
And with last update the fault keeps opening randomly IN MY CURRENT TAB!
This extension is utterly useless. And i must say that it's really hard to trust a company with my passwords when their browser extensions are so badly made.

Garbage. Installed 4.16.1.1 on FF ESR-60 on Linux and no extension icon - have to use website login to access vault. Sort your testing out lastpass, this product is not fit for release.

Not working to copy/paste the credentials manually without the desktop app. Rubish

created a firefox account specifically to write this: Lastpass add on sucks.

I've used it for years, telling my friends to use it, but it has consistently sucked for the past few months.
I'm using 1password at work and it is miles ahead in terms of reliability.
Lastpass addon will often fail to autofill, or fail to save a new password when creating an account (it just did right now for my firefox account, I had to create it manually).
Save your time and use another of the many competitors.

Will not work correctly after getting updated to WebExtension plugin. Some websites do not get filled with credentials, and there are no buttons to just copy/paste the credentials manually.

Lastpass really sucks!!! In Firefox when you click on the add-on, you have to right click to open lastpass on their website. Then when you login you can't even put in a preference for the friggin thing to stay in list view or grid view or to keep the folders closed. When you launch one of the websites in your list, the friggin thing doesn't even insert the username and password; you have to do that friggin manually. There are a lot better password managers out there. Don't waste your time with lastpass!!!

18 attempts to create an account and be able to login = 18 failures!

bug :(

Flakes out regularly. I'm going to switch away from Lastpass as soon as my subscription runs out.

Very buggy extension

August 3, 2018: I have used the LastPass extension for years as a plug-in to Firefox without any difficulty. However, the latest version of the LastPass plug-in fails to integrate with Firefox 61. The only way to use LastPass from Firefox is to go to lastpass.com and login there. I logged the problem on the LastPass website last week. Not clear to me whether this is caused by a change in Firefox or in LastPass, but regardless, it renders this plug-in useless.

Downloaded latest version of Firefox, and now Lastpass add-on doesn't work. (But it still works fine in Pale Moon.) Guess I need to start using Pale Moon as my primary browser. Sorry....

After Browser Restart i always have to relogin manually.

I reverted to an older version 4.9.1.1 and set my addons not to auto-update. I will not be renewing my lastpass premium membership if they don't start providing better addon support. Older versions can be found at https://addons.mozilla.org/en-US/firefox/addon/lastpass-password-manager/versions/

Lastpass has been going down hill since Logmein bought it. Lastpass has gotten worse with every Add-on.

It opens a web page every time I launch Firefox and asks me to create an account or log in WHEN IT'S ALREADY AUTOMATICALLY LOGGING IN FOR ME WHICH I PREFER. But apparently the software doesn't register that.

More update, more problems. Nice try LastPass. Doesn't justified for those customers on Premium subscription.

Used to be very good and now it simply doesn't work properly in Firefox! I have uninstalled and re-installed, and still buggy. Auto Login doesn't work; have to click several times to get LP to open. Less functionality in FF than Chrome. Stay away until they fix it!

Lately Lastpass is filled with bugs will not recommend for a new user

Ganz o.k. aber entwickelt sich immer mehr in eine nervige PopUp Lösung. Jüngstes Beispiel "GetStarted" Seite die bei jedem Browserstart ungefragt aufpopt und sich nicht deaktivieren lässt.

click on the icon of lastpass and nothing happens. FF 61.0.1 x64.

4.16 Sucks

Autologin not working. Have to press LP icon in a toolbar every time I start browser, which will open "Safe" after login, overwriting current browsing page. Very buggy!
