I spent hours updating my bookmarks and firefox crashed and to my delight all my changes were undone. I verified this at least 20 times. Reproducible: Always Steps to Reproduce: 1. 2. 3. Actual Results: delete a book mark restart Firefox it is back. add a bookmark restart and it is not there. change the name of a bookmark and restart Firefox and the old name is back. Expected Results: Before all my changes were saved, I expected all my changes to be saved. Otherwise what is the purpose if your bookmarks cannot be changed? I lost hours of work that is very critical to me. Also if the bookmarks will never work again I will delete Firefox permanently and I am certain many others will also so it should be critical to you.
Any time you restart firefox the bookmarks return to what they were before.
