Firefox Community Forum

I've use Firefox vpn for some time now. Suddenly any attempt to access a website, including the lovely link to my kindle book suggested by Firefox results in this: Secure Connection Failed

The page you are trying to view cannot be shown because the authenticity of the received data could not be verified. What can you do about it?

The issue is most likely with the website, and there is nothing you can do to resolve it. You can notify the website’s administrator about the problem. message. Firefox is blocking me with no way around??? Regular firefox now just doesn't download! I want to congratulate your implementation of a security nightmare with zero testing. Please tell you product development and marketing folks that they won't have to worry our reading and acting on any of your advertisements!

I used Firefox this morning and it worked normal. This evening however it will not open as normal. It appears to want me to create a new profile. It does not have a toolbar or any of my bookmarks What do I need to do to restore

When opening websites the images are not opening, only blank boxes appear. I don't have any settings for security causing problems because I turned them off previously. simply cannot find what is driving this. Thanks, Don

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

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.
