Cannot Login with Firefox Private Tab anymore

[mbeh116]

Hey guys,

First of all: I have not changed my settings or installed an update. I'm using 2-F-Auth and (also because of that) I'm pretty sure that nobody hacked my LP account The PW is correct (I can log in via Chrome) and yes, I've already turned the PC off and on again in the meantime

Yesterday I realized that I can't login with my Firefox browser anymore - neither with the extension tray nor via the login page of the extension. When I start the browser I get the question if LP is allowed to track my tabs - fair enough - accepted. But still I can't log in. What is going on here? Is Lastpass now only available for those of us who provide all their data (including those unnecessary for the program)?

I have the same problem. I have Firefox set to always run in private browsing mode. The latest release of the browser extension (4.31.2.3) for firefox now breaks completely. I can't log into lastpass.

I have the same problem. I use Firefox in Private mode as default - why would you do anything else?
To login to LastPass go to lastpass.com and login there. I use a YubiKey for 2FA, and I notice quite a delay before my YubiKey code is accepted, but gets there eventually.

Thanks Badja, I went to lastpass.com and was able to login fine.

I have the same issue as of August 15th 2019.

Extension version: 4.31.2.3

FF Version: 68.0.2

Windows 10 (1903).

I use FF in Private mode by default, I turned it off as an experiment, and it still does not let me log in.

Like others here, I use 2FA, but never get the prompt for it.

I have successfully been able to log in via the web site with the same FF browser (with 2FA), so it should work, but the extension is somehow broken.

Adding a +1 to this issue. I launch Firefox, click on the extension and am shown a permission request page. I accept these and then attempt to login. Once I've entered my username and password I see a red spinning circle that doesn't progress to the 2fa prompt. I can successfully log in via the website, but this is a tedious workaround.

Has anyone from LastPass seen / acknowledged this issue?

Note that the guys on this post seem to have the same issue:

A work around - almost.
I've still been able to login via lastpass.com, but this time it took 3 attempts for the login to give me the red square on my browser meaning I could actually use Lastpass. The previous logins gave me access to my vault, but not auto-fill from Firefox.
If you find that logging into lastpass.com doesn't work, just keep trying. It worked for me eventually.

As a work around, you can revert to the previous version of the extension.

Just uninstall the extension, then add the previous version (4.29.0.4) from here:
https://addons.mozilla.org/en-US/firefo ... /versions/

It actually still works for 2FA.

NOTE: this issue is happening in non-private mode Firefox as well, so it looks like the extension is completely broken for 2FA users.

Thanks @jc2645!

Confirmed, rolling back to the second to latest version fixes the 2fa login. Looking forward to an update coming out soon to fix this.
