Quantum broke Last Pass binary features. It's still not repaired and as a premium paying customer have spent hours wasting time with with incorrect solutions from their atrocious support trying to get answers. Was told to use Chrome. Told them I have used FF for over 10yrs for good reason and not about to change. Requested a refund, was told 9mths in, no refund. And I have trusted them with my passords! https://lastpass.com/support.php?cmd=showfaq&id=826
Currently back to desktop password manager, while I consider using Firefox's inbuilt password manager.

Re-prompt for passwords is currently broken. Says the password is incorrect; however, if you log out and log back into LastPass, it will then accept the reprompt password as correct.

I used LastPass for years, but no longer as of today. I'll validate the previous negative reviews submitted here today. It took the LastPass developers until the zero hour to come up with a new version that would work in the latest (more secure) version of Firefox--and LastPass is still broken. I'm constantly having to go to the LastPass vault, enter my master password, view or copy my password for a site that LastPass is refusing to fill for me, and then paste the password into the site's login. I refuse to do this anymore. LastPass is now, in my opinion, a piece of junk. I've switched to DashLane, and so far I'm loving it. Goodbye, LastPass!

I love LastPass. But this review is specifically for the Firefox extension, which was last updated 19 days ago and still doesn't allow simple functions such as "copy password" and still doesn't remember my email or my preferences (such as opening my vault upon launch). And when I do log in, I have to click past the LastPass Families ad EVERY TIME. It wouldn't be such an issue if the app didn't have paying members (which I am). There's no excuse for this, LastPass. You've had 19 days since the last update, and you had months of lead time before that. Shameful.

Read what what David P. wrote, and double it. It is garbage. It used to work well, and was safe. ANYONE can get to your passwords now - that is, if it even "decides" to autofill!! It is crashing my browser EVERYtime. It doesn't autofill anymore. Hacker are bragging online about how easy it is to steal passwords, calling Lastpass a joke. AND, IF YOU DO BANKING ONLINE - TRUST ME - DO NOT INSTALL THIS. God I miss the days when Norton worked on Firefox. Do NOT even bother with this POS.

Unable to login

1. Connection problems on browser start.
2. Sometimes it log in on start, sometimes not.
3. Inconvenient UI and awful Russian translation. And there is no ability to change language. It ignores language setting in extensions preferences and account preferences.

Finger print authentication and log in not working with Firefox 57. I have installed the new binary extension but it still does not work.

Didn't have their extension finished in time, while they had a year to work on it. Deleted my account, and not a paying costumer anymore :)

There's enough other ones, that are less of a resource hog!

Everytime I restart my computer I have to enter a authentication code (2FA). The "remember-device-for-30-days"-check box isn't properly.

Thats very annoying.

German translation is sometimes incomplete.

Can't even login, the window just disappears

LastPass was giving me problems after the Firefox Quantum update. Every time I closed my browser and then re-opened, I would be logged out of LastPass. Sometimes while using the browser the LastPass icon would change from red to yellow or black and give me an error message about my internet connection. Here is what worked for me. I clicked the LastPass icon, logged in, and went to 'more options', then 'about LastPass'. That screen gave me the version number I was using and also the option to download the binary component. After downloading the binary component, LastPass has been working properly. Good Luck!
NEVER MIND THIS POST! SOMETIMES IT WORKS, MOST OF THE TIME IT DOESN'T!

The Web Extension version is really rough around the edges and is missing quite a bit of functionality due to the lack of binary extensions. Terrible move on LastPass' part considering firefox is still a major browsers, and quantum is a really good update.

Update: Lowered rating from 2-starts to 1-start. The autofill functionality has been really really bad on media heavy websites. That combined with the lack of binary features makes this version nearly useless.

Problems with Firefox 57

Nothing about this extension works in Firefox Quantum.

Note to Lastpass and Logmein: You ought to be ashamed. Because good grief -- what a mess. Lastpass in Firefox was cool, useful, and glorious -- until LogMeIn gobbled them up. Now it's inconsistent and VERY buggy.

It won't keep me logged in, for instance, despite it explicitily being told to keep me logged in. Sometimes the icon on the toolbar works, sometimes it doesn't. It can't seem to always recognize the site I'm on; nor does it autofill the correct password.

Send in a trouble ticket and the dope says he's replicated it and it's been sent to the developers, something that happens regularly.

Save your money and try Bitwarden (Google it). It's new and not as robust as I'd like, but it's free ($10/year gets you the premium) and the developer actually responds and adds your suggestions to his to-do list.

Don't lock your p/w data up with this propriety (and not always secure) solution. Suggest the free (opensource) "Keepass" (which also has nice multiple (quantum compatible) add-ons for automatic p/w filling.

I am just done with Lastpass. I have used this software for years now and it seems every time they "upgrade" their add-on or a browser updates, Lastpass ends up terribly broken. Come on guys, it can't be that hard to keep your software running. Either fire your staff, find coders that know what they are doing or shut down your company. Lastpass is not worth the headache. Looking for a better password manager that actually works because Lastpass simple does not.

lost passwords!!!

Virtually useless under FF57. Don't know if that is Mozilla's fault or lastpass's but I had to downgrade both to get all the features back. Glad I didn't renew my subscription this year.

FF add-on does not authenticate on Android. The Lastpass App does not recognize websites opened with FF on Android. So, LastPass is nearly unusable forth Firefox on Android.
