- FF Sync will save my bookmarks (including Live Bookmarks I hope?) - The Sage extension will import OPML feeds. Not been updated for a while though it still works with FF 19. - Feed Sidebar 6 and OPML Support 1.6 is another alternative. - Bamboo Feed Reader 1.7.4 also works quite well. I can set up each one of these combinations in their own Firefox profile and play with them until I find one that suits my needs. - Nick B.
