Facebook container in FireFox 105 for Windows 11

When I installed FireFox on my macOS Mojave years ago, the Facebook container was there by default.

But when I installed FireFox on my newly Windows 11 laptop a few weeks back, it didn’t come with Facebook container - can I know why the difference in setup ?

I want to provide a use-case of not inerting the Facebook tracker on our website’s source. But majority users are on Windows 7/8/10/11.

The Facebook container can be installed here: https://addons.mozilla.org/en-US/firefox/addon/facebook-container/.

Did it come by default when FireFox is installed before ? Or do we manually have had to install the Container extension ?

I am not 100% sure since the early days of it has been before I joined but I don’t think it’s been installed by default.

Everything I was able to find from earlier referenced installing it from addons.mozilla.org.
