Windows 10 Accounts Port Gary Guo کی جانب سے

Starting in Firefox 91, Firefox has direct integration with Windows SSO so this extension is no longer needed. Please check out https://support.mozilla.org/en-US/kb/windows-sso for how to enable it.

Sign in to supported websites with accounts on Windows 10. Ported from the Chrome's Windows 10 Accounts extension.

Windows 10 have a native messaging host for Chrome preinstalled. To make it work for the Firefox port, the following steps should be taken:

Create a file C:\Program Files\Windows Security\BrowserCore\manifest-firefox.json with contents
{
"name": "com.microsoft.browsercore",
"description": "BrowserCore",
"path": "BrowserCore.exe",
"type": "stdio",
"allowed_extensions": [
"{d4a5b766-4831-43f0-9d38-0fec359491e7}"
]
}

Then execute
REG ADD "HKCU\Software\Mozilla\NativeMessagingHosts\com.microsoft.browsercore" /ve /t REG_SZ /d "C:\Program Files\Windows Security\BrowserCore\manifest-firefox.json" /f

to add it as a native messaging host. You can also replace HKCU with HKLM to add for all users.
