Where are your favorites stored?
Favorites (also known as Bookmarks) are a collection of direct links to a frequently used page or site. Adding a link as a favorite provides a user quick access to links such as knowledge articles, incidents, catalog items, modules, etc.
The favorites are stored in the Bookmark (sys_ui_bookmark) table.
1) On the Navigator, go to System Definition -> Bookmarks.
This will display a list of favorites for all users.
