Instead of returning directly to my desktop when I close Firefox, this website opens: https://www.websudoku.com/ and I then have to close that before I can see my desktop. I do not want this to happen!!!!! How can I stop it?

Is there any documented way our I.T department can disable the ability to connect to or even see the Firefox VPN that is being rolled out via group policy or another settings method? Firefox is a great asset for our agency but we cannot have users having the ability to bypass our web filtering. If there's not an option currently, could we have the IP's or the servers that it runs off of so we can manually block it in our firewall?

I'm sending this from my phone. My desktop FF (Win 10) suddenly displayed a black wireless globe type icon called Prox-Media pinned to my taskbar. I can't find the app on my system, though, but the full path leads it to a firefox.exe file. Before my brain kicked in, I'd clicked on the icon right after noticing it, and Firefox came up with the attached error message displayed.

"Prox-Media" comes up nowhere in my searches - not as legit, not as a virus - just no results. Can you help?

I have a paid AVG account and I ran a deep scan but it found nothing.

I recently opened Firefox to see a new flagged warning under my toolbar that says "The security sandbox is disabled. Your configuration is unsupported and less secure."

I have gone into about:config and adjusted every security.sandbox element to see if that would change anything; it did not.

I am running on Windows 11 Home so I cannot install or properly run Windows Sandbox.

I would either like a solution to enable the sandbox once again, or just remove the notification from the toolbar.

I need to install PKCS#11 modul on iMac (OS: Ventura 13.7.4) for signature authorization. I try: Settings-> Privacy and Security-> Certificates-> Security devices-> Load-> Modul filename: /Applications/CertiliaMiddleware.app/Contents/pkcs11/libCertiliaPkcs11.dylib , but I get an answer: "Unable to add modul". In order to install a certificate for signing with a card, I was informed that I need to install this modul first, but it doesn't work. What should I do? Thanks, Martina

Hi, I am using Firefox exclusively for my work Claude account, I only check my usage on it. Today, I noticed Firefox silently installed a webapp under $USER/AppData/Roaming/Microsoft/Windows/Start Menu/Programs, and it has a Claude webapp, which I neither click any install or add to my menu. I found it extremely concerning in terms of privacy, and I am wondering if any other people have similar experience.

Also McAffee notification with all these popups stating that my McAffee protection expired yesterday - I have never had a McAffee notification for a virus or pair for protection from them. Popups are happening every 10 seconds continuously! looks like about 20 or more popups describing different problems with 20 digit numbers and letters as a serial number of the problem!

Hello,

I am running windows 10, firefox 148.0.2 (64-bit) and when signing onto amazon.com I am greeted by this annoying pop up. Screenshot attached,

"Windows Security Making sure it's you

Please sing in to amazon.com This request comes from Firefox, published by Mozilla Corporation"

I do not find a need for this pop up and would like to know how to disable it. If you know how, please let me know!

The title. I want to be able to browse while trusting a specific CA certificate, but have the option to browse without it as well. If there is no way to do it, is there a way to toggle whether Firefox trusts a CA without needing to reinstall it every time?

When the AI chatbot is enabled in the sidebar but "collapsed" -- the tool not engaged -- is any data sent to the chatbot provider? Can the chatbot be collecting data while not engaging with the user? Or is context sent only with prompts and limited to the tab that is open?

What sort of sandboxing is enforced by Firefox?
