Re: Logging into LastPass Firefox extension results in An unknown error occurred

tektune describes the problem I'm having perfectly. Was able to get in by browsing to lastpass.com and logging in there, on the web page. Extension login completely broken. Am getting the same error on browser Extension. Running Firefox 80.0.1 and latest LastPass (have removed and deleted it several times today).

 

Version 4.56.1.3

Re: Logging into LastPass Firefox extension results in An unknown error occurred

This version also has a problem with Duo Security's multifactor authentication, since when it requests the key from the key list that is sent by SMS, it does not indicate which position.

I opened a thread with this:

Re: Logging into LastPass Firefox extension results in An unknown error occurred

I am also experiencing the Firefox login problem.  I use Firefox every day and I use LastPass every day.  I always use private browsing mode and do not allow firefox to remember any credentials.  I also use LastPass Authenticator.

 

In my experience, every day I have to authenticate with LastPass through a webpage when I click the extension icon.  I've never received the pop-up login box in Firefox.  Today I received the new unfamiliar pop-up log box.  This is problematic on its own because I don't know if it's a malicious extension trying to phish my master password.  The fact that we can randomly get two different login boxes is worse.  Ideally every time the LastPass extension is auto-updated, it would alert the user to any changes to the master password authentication process so we can maintain confidence in the application.  This should never randomly change.

That said.  The new login box always returns "unknown error".  I had to go to lastpass.com manually to authenticate.

Re: Logging into LastPass Firefox extension results in An unknown error occurred

Me too. It's clearly not an isolated problem.

 

Right now, when I open my vault, I have the offending box "behind" the items in my vault.

 

I'm not sure how to find the version of Lastpass I'm using (although there's no reason why it should be out of date). I go to More Options -> Help, but here's nothing usful there.

 

Also - can I attach a screen shot to a post?

Same problem here. It started last Friday. I installed  Google Chrome and Edge, and in Google Chrome only I can login. Very frustrating.

I have the same problem. I am running the latest version of FireFox v80.0.1.

The login does not reconize my password.

Re: Logging into LastPass Firefox extension results in An unknown error occurred

I can no longer login to LastPass using Firefox v55.0b2 (64-bit) Developer Edition and LastPass v4.51.0.1. It has been working fine for several months and the problems started a few days days ago w/o installing any new extensions. I get a new login screen and an error when I try to login:

b52490a194ec4e541f47bb36fac6e4be

(I removed my E-mail address from the image).
The E-mail address is also not saved, even though checked.
I also tried to upgrade to the latest version of LP
(v4.56.1.3) but it made no difference.

 

 

 

p.s. It still works fine for me in the latest version of Firefox (v80.0.1 -64-bit) and LP (v4.56.1.3) and in Chrome.

Re: Logging into LastPass Firefox extension results in An unknown error occurred

I've noticed no one from LastPass has replied.

Do they monitor this thread?  If they don't, are we talking to the wind?

I've been using LP for years, and really loved it. but if they don't fix this FAST, I'm going to a password manager that works. Or at least one that we can contact and will fix a major bug
