[Feature] Option to Enable Bookmark Menu

[justaguydoinghisstuff]

Hi,
I would like to suggest adding a new feature.
Firefox Multi account containers have an option called "Enable Bookmarks Menu" which is super useful as it allows people to right click a folder in the bookmark menu and open all bookmarks in a particular container.

This is useful if one person has a set of websites he wants to open frequently in a particular container but cant set the rule to always open in the chosen container.

Ill try to make a real life example:
I have a folder in my bookmark toolbar called "Reddit" with lets say 5 bookmarks in it of the subs that i like to browse frequently
-reddit.com/r/sub1
-reddit.com/r/sub2
-reddit.com/r/sub3
-reddit.com/r/sub4
-reddit.com/r/sub5
With MAC i can right click the reddit folder and choose to open all of them in a particular container i.e "reddit2"
I cant set up that all redit sites open in "reddit2" container as then it makes it near impossible for me to open reddit in another container i.e. "reddit1" where i have a different account logged in.

This is not only limited to the reddit example but it was the easiest one i could make. Another use case would be if you use the Gsuite and need to open multiple of its services(mail,calendar,drive,classroom) daily but again cant set to always open in one container as it will prevent you from using both Work and personal account toghether (wich is one of the main features of containers)
