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.

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.

Not working in ff57 for Android.

The add on would NOT authenticate with LastPass. I could go to LastPass weenie in browser tab and login & authenticate, but still no succuss with getting the add on to work.
So no LastPass functionality with Firefox.

Not working

This extension for Firefox 57 barely works. Whereas previously LastPass would automatically fill in the fields and connect to most websites without user intervention, it now does that for none of them. At the very least, one has to scroll and find the appropriate site and click on it to enter the data fields. In most cases, a second click is required to send the data to the site. I have found at least one site where the new extension refuses to display or enter the user or password, requiring that it be done manually. After LastPass support's suggestion that I use the "save all entered data" for this site failed to work, it was suggested that I install Chrome and try the extension for it.

Firefox announced its new standards for FF57 extensions in February. LastPass did not release this extension until the day before FF 57's release and the extension it released is full of bugs. When I filed a support ticket as a premium user, LastPass acknowledged that they were aware of these issues. However, it was made clear that there is no target date to fix them. Despite the foregoing, no attempt was made to warn users about the lack of functionality of this extension. To say that LastPass has "dropped the ball" in its release of this extension is to put it mildly.

Was working with Firefox Quantum (57) earlier, now unable to login. Also, unable to save email since Firefox 57.

Not working on Firefox for android. Not loging in to lastpass.

Entirely non-functional. Takes dozens of tries to log in, then once it has, pops up desktop UI elements in tabs instead of incorporating into the mobile browser in any way. Even within that menu, nothing actually responds to click. Have had a support ticket ignored for a week now.

Unable to log in

Sorry man
