Firefox Community Forum

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.

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?

Hello,

I am a bit confused and worried about what is happening here. I am routing Firefox through controlD DNS and Reddit.com is the only website that it doesnt block even though its on my blocklist. I tested it with a few other websites too and those did get blocked on Firefox but not Reddit. I did some testing and it seems every other browser works perfectly fine. Is this intended for Firefox to route Reddit through their own DNS servers instead of the private one I have setup? This is a bit concerning to me.

Let me know if this is intended or why this isnt working only on Reddit.

I am getting repeated pop up "alerts" from Firefox, McAfee and others about Trojan Horse and other viruses. I did not click on the links offered. How do I stop them from coming?

I am using version 143 for Linux and it is suppose to have improved fingerprinting protection. But when I go to https://coveryourtracks.eff.org i still see a result that says "your browser has a unique fingerprint"

Is there a parameter I should be enabling ?

Lately, I have been noticing that new Firefox browser windows (not a new tab, a new window) have been opening seemingly randomly on me. The sites in these new browser windows are always commercial in nature and seemingly random in subject matter. I am not aware of having clicked on anything that would cause the new browser windows to open. I need to know how to block this from happening; I am unable to figure it out in the various Firefox Settings.

my favorite browser firefox isnt enough help to keep my privacy secure (Its 100% confirmed)

I just learnt that my internet provider is blocking some domain like web.telegram.org which is very annoying. The solution i found on internet is vpn or tor browser.

Am i expecting something from firefox that it cant help me with?

A free vpn or tor browser like functionality?

I am so sorry to go away from it but look like if there is no way firefox can help me secure my privacy then i will have to.

Please try to be friend and help like a friend
