Bookmark all selected tabs, not just the active tab [request]

[spiralsam]

When user selects multiple tabs using Firefox's tab bar (ctrl-click or shift-click individual tabs in tab bar, or right-click tab -> "Select All Tabs"), multiple tabs can be "selected".

QuickBookmarkToFolder acts only on the tab that is currently active and in view. Request to add support for: QuickBookmarkToFolder acts upon all "selected" tabs.

Useful feature and easy to implement.
Should have an option named "Save multiple tabs in separate folder". While by default it saves them as individual bookmarks directly within the search folder.
