Firefox has always been slow to load at start up, and its a chronic problem now. As the Firefox installation gets older, it gets slower. I think one of the main reason is that Firefox stores the information in Sqlite database, and it takes time to gather that information on startup. So, the more bookmarks, or the more extensions you have, more time it will take for Firefox to startup. Also, Firefox checks for add-ons updates on startup... and that also contributes to the delay. That is my understanding of it.. and I am not sure of what I wrote... but it should be true, if my logic is correct. That's why various utilities which claim to make Firefox faster, use vacuuming of the database of Firefox.
