One thing that I was dreading about this Safari-for-a-week thing was having to manually copy over my bookmarks from Firefox.  There’s not much worse than wasting a bunch of time doing copy, paste, repeat.  A little Google search, and we have a winner!

If you’ve got Safari 2.0 (or higher) you’ve got import and export options in the File menu. Choose Import Bookmarks, then navigate to bookmarks.html in your Firefox profile (~/Library/Application Support/Firefox/Profiles) and click Import.  

Emphasis mine. So simple, yet almost too simple to believe. Time saved; color me happy.
