Firefox container option not showing in windows
The option for opening each tab in container not showing in Firefox for windows. I have the latest version of Firefox(87.0).
Please check if there is any extension that is blocking the Firefox container option. Moreover, also check that
is set to true.

You can try to hold the left mouse button on the new tab plus button to see if that opens the container menu.
