I am suggesting extending bookmark operations to a multi-tab setting. There has been some discussion and implementation of multi-tab operations, see https://bugzilla.mozilla.org/show_bug.cgi?id=566510#c37 There are three ways to bookmark the current page: 1. right-click on the "favorite" icon 2. open the Bookmarks menu 3. press "Ctrl+D" All three open the same "door-hanger" dialog. In order to implement the same operation for a multi-tab selection, the dialog needs to be aware of the presently selected tab multi-set. The ui can remain unchanged, but the three fields (name, folder, tags) will have modified operations: name: This becomes the name of a newly-created bookmarks folder. The folder is populated with bookmarks of each of the pages in the selected multi-set, using default values for their individual bookmark names. folder: The folder to nest the new folder named "name" under tag: applied to the folder Any thoughts?
