Well done Firefox team. I got a notification this morning telling me I could update Firefox to the latest version and I had nothing urgent so I did. Imagine my suprise when all my bookmarks, my passwords and logins appeared to have disappeared. Well, not just "appeared", since I can't find them anywhere on my machine right now. I've been using Sync for years and when I finally managed to connect (because apparently the password I had been using was wrong ? But did FF tell me ? No ...), I discovered nothing had been saved. Ever. A really nice morning.
