Hello, I want to be able to use containers when using Mozilla. I followed the instructions from the support article Multi-Account Containers link here: https://support.mozilla.org/en-US/kb/containers but was unable to do anything other than install the extension. I have no access to a containers icon despite looking in my toolbox, settings, and extensions. When I click on tabs I am unable to put tabs into containers despite following the presented instructions. I also find that in settings I have the message "Firefox Multi-Account Containers requires container tabs". I thought that downloading the extension would allow for container tabs but I am unable to even find the option to open containers. I've attached some images to provide context as to what I am seeing. Any help you could provide would be greatly appreciated.
