Prior to Firefox 57 (version is now 58.0.2) LastPass was a very valuable tool, even essential. Tried Firefox 58.02 and LastPass 4.2.3.20 add-on and always reach the same insurmountable problem: every time the browser is closed and re-opened I have to log-in to LastPass using my master password (a long and complicated password).

With Firefox 56.2 (and earlier) this was NOT required and LastPass opened automatically upon each Firefox session starting.

As a result, I re-installed Firefox 56.2 and missing out on better browser security for the sake of keeping LastPass log-in active, even after re-booting my PC. This is apparent on Windows 7 and Windows 10, so can't blame Microshaft this time.

Same problem exists with IE11 on both Win7 and Win10. Something is not communicating well between FF 58.x and LastPass 4.2.3.x

Like others, I am looking for a better (?) password manager.

As Android version is officially abandoned (see https://forums.lastpass.com/viewtopic.php?f=12&t=280445&start=80) - this extension became useless. Everybody uses mobile phones and everybody wants to use the same browser on desktop and on mobile to make use of sync, tab sharing etc.
LastPass app for Android without this extension doesn't fill in form fields in Firefox too.

Bye, LastPass! I switch to bitwarden, which works OK on Firefox for Android and offers more for less money.

The Firefox extension doesn't have a quick copy username/password like the Android and Chrome extensions. It's quite annoying to have to open my vault every time I need a password. Otherwise it seems to work fine.

You can find the solution to "I trusted my computer, but still get prompted for Multifactor Authentication" in the support page of LastPass.com, try searching in your duckduckgo or google.

Use to be a great addon but now there are login issues. I now pay twice as much for "Premium" upgrade and feel these issue are unacceptable.

SO messed up. I can't use it, hell I can't even find it. What did you do to us? Get a clue by the thousands of 1 star ratings and do something to remedy this issue before you have no users left. I am tryig to find a way to remove it right now and I used to love this app.

Broken; cannot log in anymore

I used to use the LastPass addon a lot on my Android phone, but it became unusable after Firefox Quantum came out, and they still haven't fixed it. The length of time that this problem has gone unsolved is not acceptable.

1) Generating a password for a new website is not seamless. At least not as seamless as Chrome.
2) On some websites, it's unable to fill in credentials into the boxes. The same websites have no trouble on Chrome

When it works it's great, when it fails like its been lately then it reminds you every 20 seconds that there's an Error. Might be time to find a new password saver manager.

I've used lastpass for years on desktop and android. I cannot get it to work at all Firefox 57 - attempting to login just produces a spinning cursor.

As a mobile Firefox add-on, Lastpass has NEVER, since october or november 2017 I think, managed to log in to the online vault with the passwords.
As a standalone app, I can login and view my credentials, search for website, username, copy password. But from within Firefox, when I click the Lastpass button in the login fields, it will loop forever trying to log in to Lastpass, without success.
