Hi,

Since last week I am unable to properly use some websites that are failing due to CORS requests, but they were working before. Some examples are es.webuy.com or a local Jellyfin instance. After trying to enable/disable some settings that I thought could be related to the problem, like security levels, I ended up creating a new profile. In this new profile everything works, but as soon as I synchronize my Mozilla account, then these websites start failing again with CORS requests errors.

Any idea about what setting might it be the one causing problems? Or any idea about how can I debug/troubleshoot it myself?

Thanks!

WHAT THE HELL IS THIS???

I can't delete the malware "Startfenster. I tried to find help with "Google"-Search. Without any success! This malware exists for me in "Firefox" only. Other browsers are not affected. Perhaps anyone can help me... Thank's!

We’re experiencing intermittent OCSP issues where all our internal sites fail to validate certificates. The problem appears random and sometimes resolves by simply closing and reopening Firefox.

One of your forums mentions disabling OCSP checking via the UI, but that option is no longer available in the latest version (147.0.1).

We’ve temporarily disabled it via about:config by setting security.OCSP.enabled to false.

Is there a permanent way to disable OCSP checking that can be enforced via Group Policy (GPO)?

Windows Defender is blocking Yandex.Ru, which is not even been tried to be access from. It showed in the Event Viewer that firefox.exe tried to reach Yandex.ru. Why is Firefox trying to reach there? There are no extensions apart from Firefox Multi-Account Containers installed.

Please advice.

This happens occasionally for many months. It is still happening on v147.0.1. I start the computer, open Firefox, and the browser loads previously viewed pages, including my Gmail account. The Gmail page has me already logged in, and I DID NOT provide my password! This has to be a big security risk. If some one were to use my computer, or it was stolen, they would have complete access to my Gmail and all Google properties! OS - Debian GNU/Linux 12 (bookworm) Kernel v6.1.0-42-amd64 Firefox v147.0.1 (and MANY previous versions)

Right below the search bar my browser has a warning "The security sandbox is disabled. Your configuration is unsupported and less secure."

I am on Windows 10. I have tried uninstalling firefox, removing appdata and all other firefox files and settings, resetting about:configs settings, disabling my BitDefender antivirus. Nothing fixes it. Completely fresh install of firefox still gives me that message. Sandbox level is default (9).

Any help would be appreciated.

I went to youtube account of Jack Storm Jack Storms | The Glass Sculptor - YouTube; I tapped on his "website" and the next thing I know are the at least 3 side messages regarding a virus. I have attached one photo of said message.

this is another: https://berht-shv.com/zclkvisitor/9a3fb513-fa41-11f0-acfd-12edde5c536d/85aefdc2-9ed0-48aa-922d-60f9f9fc0f2d?campaignid=9a50f321-fa41-11f0-acfd-12edde5c536d

Please direct me as to next moves. I did put on strict.

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.

A pop-up screen often appears when I use Firefox. It says hat I have a virus and that I need to call a phone number to remove it. It claims to be Norton,but I doubt that it ts. I have attempted to remove this with Microsoft Defender, SuperAntiSpyware and Trend Housecall but none of them work. Can you help me?
