And not only the bookmarks, the history file also loses all previous connections. I think (suggest) what, if it was posible, it must implement some mechanism for backup as temporal files, while mozilla is open, for this type of files. So that if mozilla crash (machine problem for example) the loses are not total. Reproducible: Sometimes Steps to Reproduce: 1. 2. 3.
