My Teams will not open on my pc laptop. It's tiny icon only flashes, I tried to sign in to microsoft and to the old skype but am told my passwords were compromised in 2024 and am sent to archive.org to change. I do not understand this archive site or what I am to do. Are their any interpreters for those who can't find direction? Thanks so much

I had a problem where FF 140.0 would not update, and in trying to get FF yo update, I used a re-install tool to which I was pointed in my problem report. This caused FF to wipe out my configuration, and I lost all my windows and tabs. I have gone to

    \Appdata\Roaming\Mozilla\Firefox\Proifiles\abnfpged.default

cleared all of the data therein, and restored that directory from a backup I made last Monday. But I cannot get FF to use that directory. "about:profiles" shows only two profiles, but the Profiles directory has five profiles:

03/10/2026 09:39 AM <DIR> qf00ka5x.default 03/10/2026 09:39 AM <DIR> v842ceue.default-release 04/11/2026 09:16 PM <DIR> .. 04/11/2026 09:16 PM <DIR> . 04/12/2026 03:08 PM <DIR> abnfpged.default 04/12/2026 06:29 PM <DIR> jdfj91sd.default-release-1775960183850 04/12/2026 06:48 PM <DIR> f1jq4mlq.default

Only the profiles beginning with "j" and "f1" are seen in the "about:profiles" screenshot I have attached. And I have attached a screenshot of my profiles.ini file. Also, in the abnfpged.default directory I restored, where is the list of all of my open windows and tabs? FF used to keep that in a sessionstore.jsonlz4 file, but that file is only written when FF closes. I tried to save a copy when I was having problems, but I stored the copy in the same directory, which FF changed during the re-install process. Here is my profiles,.ini file:

[Install308046B0AF4A39CB] Default=Profiles/jdfj91sd.default-release-1775960183850 Locked=1

[Profile1] Name=default IsRelative=1 Path=Profiles/f1jq4mlq.default

[Profile0] Name=default-release IsRelative=1 Path=Profiles/jdfj91sd.default-release-1775960183850

[Install641D10338ABA448D] Default=Profiles/abnfpged.default Default=1 IsRelative=1 Locked=1

[General]

StartWithLastProfile=1

Version=2

[BackgroundTasksProfiles] MozillaBackgroundTask-308046B0AF4A39CB-defaultagent=lnvi5jn5.MozillaBackgroundTask-308046B0AF4A39CB-defaultagent

I have not worked with the ;profiles.ini file in many years, as my FF configuration has not had problems. Thanks.

Hi

I understand that security is important, but it it is MY account, MY data, MY responsibility.

When you install FireFox on a new device, then you cannot sign in to your account without entering a confirmation code - that is 'crazy'!!

Why is it crazy, well, first of all FireFox / Mozilla know that it's a new device, so how do they suggest that I get to my email on a new device ??

It's the same as asking for a security code when you setup your email - How do you see that I can get my code when setting up the mail app ??

Imagine - god forbid - that you were to loose your phone and computer, you then got a brand new computer - even with a recovery email address, you can still not log in because the recovery email address also requires a confirmation code on a new device!

On my Mozilla account I have turned of 2FA, so why do I need a confirmation code ?

As mentioned, I understand that security is important, so please do not use that argument.

Google Search CAPTCHA persists unless you sign in to your Google account. This only happens in your browser, from versions 140 to 149. Other browsers don't have this problem. Changing the user agent used to help. Now, nothing works.

My old laptop broke so I got a new one. I logged in to firefox, but had to change the password as I didnt remember it. Firefox said "the safed passwords might be lost" but I had to do it anyways.

Indeed the passwords are gone. Is there a way to get access to these passwords? I figure if I only could use my old laptop again, the passwords would still be there.

Thanks for the help in advance...

Relevant to Firefox running on Ubuntu 22.04 Linux and an x86_64 platform.

Until roughly 2/2026, it was possible to load a security device by opening Settings, Privacy and Security, Security Devices, then browsing to a shared pkcs11 shared library, in my case /usr/lib/x86_64-linux-gnu/opensc-pkcs11.so, and clicking Load. The shared library would load and would be loaded subsequently whenever Firefox was started. For roughly the last two months, Firefox would pop up an error saying it was not possible to load the security device, but it would actually be loaded and it;s functionality would be available for the current session. For the last two weeks, the library would load without error, but only for the current session. Starting on 4/13/2026, some functions in opensc-pkcs11.so work, but not others. For example, it is no longer possible to connect to MS Teams web interface.

bold text I am getting a flood of messages about viruses from McAfee and Monzilla Firefox ESR. Not sure if these are real or a scam to click on a link. Need some help in how to stop messages or find out if my laptop is infected with viruses.

I'm using Firefox esr, the latest version 149.0.2. Since this update, I can no longer load the videos on NPR.org's home page. Something pops up, but then the wheel/circle thingie just goes round and round, and never loads the video.

My ad blocker was already off for this site. I've tried restarting Firefox in Troubleshooting mode, and changing the various security settings mentioned in this article: https://support.mozilla.org/en-US/kb/fix-common-audio-and-video-issues#w_check-some-firefox-settings, such as adding it to the "Allow popups" exceptions (never necessary before) and other settings. I've reloaded the page multiple times, restarted Firefox, etc.

Can anyone suggest anything else to try?
