The "key" to the issue is a combination of FF "private browsing mode" and the "clear cookies" setting. It seems that LP does not save any settings when the Private Browsing Mode function is checked. If you insist on this setting, forget the use of LP in FF, period, until they fix it.

However, when "Private Browsing" is unchecked and the "cookies" box is unchecked in the "Clear History When FireFox Closes > Settings", LP seems to operate with full functionality. If you can live with LP not launching the Log On page when you start the FF browser, you can leave "cookies"checked and log on to LP after you launch FF via the "add-on" icon. My LP log-on page launched with my UN saved and only asking for the master PW. After sign-on, LP launched the vault in my preferred view setting. Other functionality throughout the program remained.

So, here is the task for LasPass tech support:

1. Fix the LP program so it works in FF "Private Browsing" mode.
2. Fix the LP program so it works when FF is set to delete cookies when FF closes.
3. Fix LP to function when you enter the LP domain in the " Allow cookies from websites > exceptions" entry.

Recent updates have nerfed most of the effectiveness of this add-on, which is sad, because it used to be an outstanding password manager. Now, it frequently spams you with remember-this-password requests when they are not needed, but frustratingly refuses to remember passwords, particularly when you've just asked it to create one! (Older versions would save the password without assigning it to a site, so you could add the rest of the site info manually if necessary; this version just ignores the newly-created password completely.)

Auto-fill sometimes works and sometimes doesn't, and there's no convenient shortcut to copy a password so that you can paste it somewhere else (say, an app that LastPass doesn't directly interact with). This isn't just an issue with New Firefox (although some of the bigger issues exactly match the issues that the add-on has in Chrome, so that's part of it), but more an issue with what seems to be the direction of the company - spending a lot of time on marketing and not very much time on functionality.

The premium option was actually worth paying for at one time; I wouldn't (and don't) pay for the current version.

Unfortunately, as of January 2020 it's gotten even worse, as it seems to have significant problems with authentication - if you can't log in, then you can't use the add-on. Would love to see them roll back the most recent update or at least take a closer look at their error logs.

Was ok until latest Firefox update. Now I cannot even log in to LastPass on my Android devices using Firefox. Version 4.2.3.20

Does not work

still DOESN'T DOESN'T work on firefox for android since fx is updated to version 57

I held off a bit after 57 came out to give Lastpass time to get up to speed. They didn't, I'm running into pages where I used to be able to log in. Today I had lastpass wanting to supply credentials for a completely different site.

Lastpass was great, then it got bought, the yearly price doubled, I've always been a paying user. When my subscription comes near expiration I'm going to look for another pass word manager. Sad to see a great product turn into garbage.

As great as LastPass is on the desktop and mobile app, it's completely nonfunctional as a Firefox mobile extension. Can't even open it to login.

I like using Lastpass once it is working with the latest version of firefox, but getting there every time is a bit of a pain.

Best password manager in my opinion.

Nice app too have
