Hello! I started encountering this problem as I updated my OS to windows 11. I had eset nod antivirus, but uninstalling it nothing changed. Tried to change MTU cache size through CMD. Changed different DNSes Tried to disable all protection settings in browser and in windows settings. Deleted all extensions. NOTHING helped except clearing cache of the browser, but this is fixing problem only before first browser restart. Other browser on laptop works normally without any issues.

If Windows Pro version, try testing in Windows Sandbox (VM) to see if you have the same issue. https://www.howtogeek.com/399290/how-to-use-windows-10s-new-sandbox-to-safely-test-apps/ A shot in the dark, but also try this.

Try renaming the cert9.db file in your profile folder while Firefox is not running so that a new one is generated.

Thank you for the help. It started working on virtual machine, but as I understand this problem is impossible to fix without VM?(resetting winsock didn't help)
