Last Pass not working in private window

I'm using Firefox  with Startpage. LP used to work fine in private windows but now when I click on the extension it just opens a white box.

Any help appreciated. Thanks

Re: Last Pass not working in private window

Hi @lazza58 

 

I just tested this in the latest version of Firefox on Windows and was able to recreated the issue, after accepting the Firefox permissions the extension window loaded blank. I will check with the rest of support to see if this issue has been reported already and create a ticket if one does not exist.

Issue with LastPass Firefox Extension

Whenever I log in to my LastPass account on the Firefox extension it just goes blank after.

 

Firefox Version: 93.0

LastPass Firefox Extension Version: 4.81.0.3

Re: Issue with LastPass Firefox Extension

I can confirm this behavior after upgrading to Firefox 93.0. In my case, the blank LastPass box only shows in Private windows, it seems to work fine in normal/non-private windows.

 

LastPass still works fine in Private, it fills in my password, and recognizes when I've created a new password, the extension just doesn't show anything but a blank white box. That does make it hard to launch websites that I know I'm going to need to log into, since I rely on LastPass as a form of bookmark keeper for said sites.

Firefox 93.0 - blank Lastpass window.png

 

I concur with Christian2001's post, above. Using Firefox 93.0. LastPass works normally in regular mode, but presents a blank slate in a private window. I can manually call up a site and LP will fill the username & PW, but often rely on selecting from a list of 'Recently Used' sites from the list that is now blank...

 

I have been successfully using LP in private windows for a long time. (Since the last time it was broken several years ago) 

 

Edit: I have made sure that the latest version of the extension is installed, and that I've enabled it for use in private windows...

Hi @Robbie8592 and @cbrillow,

 

When testing on our side we aren't able to reproduce this issue, although after clicking the LastPass icon in a Private window in Firefox we did need to click "Accept" to start using the LastPass extension. Could you try making sure cookies aren't being blocked when using Private windows/tabs, and also try disabling/re-enabling the LastPass extension in the Private tab/window to see if you can then click Accept and see if the extension works as it should?

Re: Issue with LastPass Firefox Extension

Hello RachelO,

 

Thank you for your response.

 

I have experienced identical results in Private Windows on 3 computers, and have two or three others that I could also try, but there's no reasonable expectation that they would behave any differently.

 

With regard to your questions and suggestions:

"Could you try making sure cookies aren't being blocked when using Private windows/tabs..."

Please see the attached photo, at the bottom of the message, showing the Firefox privacy settings.

 

"also try disabling/re-enabling the LastPass extension in the Private tab/window to see if you can then click Accept and see if the extension works as it should?"

I have done this per your instruction, but will note that I've always had the popup to requesting that I click to Accept using LastPass. I have also cleared the cache & cookies in both Firefox and the extension.  The following link is to a 3-minute mp4 video that illustrates what happens when I login to the  LastPass extension in both regular and private windows. 

 

If there is any more information that you might find helpful, I'll be happy to provide it.

Re: Issue with LastPass Firefox Extension

I am also experiencing this issue with Firefox 93.0 on Windows 11. After clicking Accept on the Accept Permissions view, which appears just fine, the Firefox extension pop-out window is blank.

 

Firefox version: 93.0

LastPass Extension version: 4.81.0.3

 

Accept/Decline Permissions:

After clicking "ACCEPT":

Here are the steps I have completed to troubleshoot the issue:

- Uninstall the extension

- Restart computer

- re-install the extension

- Cleared cache/cookies in Firefox, closed out of the browser, and re-opened
