Bookmarks folder that doesn’t close when opening a bookmark

[Flixia]

It would be convenient if, when opening a folder containing multiple bookmarks, you could open several of those bookmarks without the folder closing (by holding CTRL, for example).

Flixia, have you tried setting:
browser.bookmarks.openInTabClosesMenu
to false in about:config?

With this setting, when you ctrl+click an item the bookmarkss menu should stay open.
