-- 1	TRANSITION_LINK                 The user followed a link and got a new toplevel window.
-- 2	TRANSITION_TYPED	        The user typed the page's URL in the URL bar or selected it from URL bar autocomplete results, clicked on it from a history query (from the History sidebar, History menu, or history query in the personal toolbar or Places organizer.
-- 3	TRANSITION_BOOKMARK	        The user followed a bookmark to get to the page.
-- 4	TRANSITION_EMBED	        Set when some inner content is loaded. This is true of all images on a page, and the contents of the iframe. It is also true of any content in a frame, regardless of whether or not the user clicked something to get there.
-- 5	TRANSITION_REDIRECT_PERMANENT	The transition was a permanent redirect.
-- 6	TRANSITION_REDIRECT_TEMPORARY	The transition was a temporary redirect.
-- 7	TRANSITION_DOWNLOAD	        The transition is a download.
-- 8    TRANSITION_FRAMED_LINK          The user followed a link and got a visit in a frame.

You can get almost all queries from daily Firefox urlbar usage from this source file: https://searchfox.org/mozilla-esr60/source/toolkit/components/places/nsNavBookmarks.cpp

Pretty cool if you want to port places.sqlite to be used globally across web browsers.
