Nothing but problems on Firefox 57 64-bit. Have the setup on three different computers and all three are nothing but frustration. Been spending a lot of time googling fixes that don't end up working. Worked with Lastpass on Firefox flawlessly for several years but the last few updates seem to cause more and more issues. A few of the problems I'm having: Lastpass keeps asking for an authorization code every time I log in despite checking the 30 day trust option. The copy username and password buttons are missing. Lastpass forces Firefox to close on different occasions. I have to click in the search box first to start typing instead of being able to start typing immediately. I use Lastpass on Chrome as well and though it is not as problematic it has its share of issues on that browser as well. I'm not sure what is going on with Lastpass lately but their extensions do not seem to be thoroughly tested.

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.

Excellent extension with a very good integration with most sites. However, it lacks copying the password from the "LastPass context menu" as it does on the Chrome extension. This means that whenever I have to log into a site with which LastPass does not integrate well, I have to "Edit" the setting and then get the password after "Showing password" on the edit screen.

On Chrome, on the other hand, I can directly copy the password without ever making it visible or leaving the website I am trying to log into.

Hope this gets addressed soon!

Not working

Ne fonctionne pas indépendamment de la connexion internet. Impossible de récupérer le cache des mots de passe de connexion sécurisées des différents sites lors de le migration vers firefox 57.0. Je mets deux étoiles pour le travail...

特别好用特别好，而且免费

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.

This program is obviously thorough. I am put my data and every format that I could think of. And then I did half of it all over again.

Used to work, but then randomly logged me out and won't let me back in, nor can I do anything about the master password. Sticking to Firefox Sync until the issue is fixed.

Last pass after inputing password get notice an error has occured, not sure what deal is, works ok in Chrome111

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

This is my 3rd install on this computer in an attempt to get browser access. Let's hope the third time is successful. BTW, it works flawlessly on my laptop, my Samsung tablet and my Samsung phone.

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.

Slow servers and lack of feedback in the user interface while loading.

Unable to log in

Inonsistent autofill results in me having to reset passwords for websites multiple times when it does not save the new password it generates, constantly reloads, very unstable.
