This is the third time that I have lost all bookmarks using Mozilla Firefox. While EI has it's problems, it does not arbitrarily without warining just "empty" your bookmarks. This is unacceptable and pisses me off!
I'm pretty sure I saw a post (somewhere) describing this very problem. There may a way to recover the missing bookmarks, but I can't recall how that is done. If anyone is familiar with the fix, please post here.
Great browser my eye...
