I-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.

I use Firefox specifically because I appreciate(d) the flexibility and the privacy. Default AI makes it significantly more difficult to customize the browser to my preferences (ie, zero AI anywhere) and threatens the privacy that Firefox is known and recognized for. This is an absolutely incomprehensible decisions; it is no longer a "trustworthy" browser if it incorporates AI. Why ruin a good thing??

Hi! I have seen that Mozilla will be moving forwards with integrating AI to Firefox. I am very uncomfortable with this, as AI poses a risk to the privacy and security that made me choose Firefox in the first place. If this is the case and AI is truly integrated (at least without an option to turn it off or opt-out completely) I will no longer use this browser and switch to something else. I enjoy Firefox so I am hoping that this will not be necessary....but we will see.

I've purposefully used the environment variable to disable the security sandbox.

How can I acknowledge and hide the persistent warning? Is there any about:config value for it?

Thank you!

I was googling something related to my game and i clicked on a Reddit search result, which i made sure is the official Reddit website not some shady one, then an empty .htm file from moz-safe-about resource got downloaded randomly. I didn't open it, i uploaded it to VirusTotal which came out safe and then i instantly deleted it and ran a virus scan with Windows Security which also came out clean. i tried to recreate this by opening the same website again both on Firefox and other browsers like Zen(Firefox based) and Chrome but nothing happened.

is this a harmless bug or should i worry that it could be a virus that didnt get detected?

Tonight I was roaming around my Firefox settings looking at something else, when I noticed this AI piece pre-checked. Why is FIREFOX, who is supposed to be for privacy and security, authorizing an update that automatically choose AI? Not cool Mozilla. Not Cool. Anyone else have this? and yes, I've already fixed it ;-)

I recently started to get a"The security sandbox is disable" warning. I have already gone into about:config

my settings:

Content Process Sandbox Level 8 Effective Content Process Sandbox Level 0 (note in about:config this setting is 6?) Win32k Lockdown State for Content Process Win32k Lockdown enabled -- default value is true GPU Process Sandbox Level 1

Firefox ver 145.0.2 (64bit)

Today as I got to work (Windows 11 machine), I had a suspicious Firefox.exe file on my Desktop, it was not a shortcut, but exe file. I did a little investigation and research, and I noticed some difference from Program Files exe file and Firefox.exe on my Desktop:

C:\Program Files\Mozilla Firefox\firefox.exe

Size: 695424 bytes SHA-256 hash: EEB242895F8ED48B43EAAA9ECA06C6DDE54425F8AE0E16200D2D46F839B9A540 File version: 145.0.0.327 Copyright: ©Firefox and Mozilla Developers Date modified: 16.11.2025 12:35 Original filename: firefox.exe Digital Signature: Mozilla Corporation

and Firefox.exe that appeared on Desktop

C:\Users\User\Desktop\Firefox.exe

Size: 389248 bytes SHA-256 hash: E8DA5735FE1B5E92BA3636B8D17B5BEC0EA521DB6A8B5A52177FF3E8B2F60710 File version: 145.0.0.327 Copyright: Licence: MPL 2 Date modified: 16.11.2025 12:35 Original filename: desktop-launcher.exe Digital Signature: Mozilla Corporation

I scanned both files in VirusTotal, and they both seems clean and legit

I uploaded both files to:

https://drive.google.com/file/d/1kALgQbfhIpHqs1pN6dmTdF71nm10LlD-/view?usp=sharing

Can somebody assure me that both files are OK, and can somebody explain to me why Firefox.exe appeared on my Desktop, and why is there difference between two files in size, Copyright info, and original filename ?

Hello, my name is Dimitris and I have pc with windows 11 and bitdefender total security installed and fully updated. Since yesterday when I open mozilla firefox a file on desktop appears with the name bd_config.cfg. I wonder whether my pc is infected with a virus or malware?

Best Regards
