This addon is superseded by Open Auto Bookmarks for added capabilities and support!
There will be no further development on this addon.
Users are encouraged to remove "Open Some Bookmarks" (if already installed) and install Open Auto Bookmarks, instead.
Please forgive any inconvenience.
This extension creates a new Bookmarks sub-Folder PopupMenu Item as follows:
Open Some - Defer Others
When Clicked, each Bookmark listed in the sub-Folder is loaded into a new Tab.
The "Open Count" Options setting then causes the first specified number of Bookmarks in the list to be opened. That is, Firefox obtains and formats each page's contents in its new Tab.
The remaining Bookmarks listed, if any, are loaded, but NOT opened until selected by clicking each one's Tab.
If the "New Active" setting is checked, the first Bookmark listed becomes the new active Tab immediately.
When Ctrl-Clicked, each Bookmark listed is opened/loaded as above, but the "New Active" setting is toggled (reversed).
