How does one know before downloading that all bookmarks will be lost?
Told AFTER the download that I should have saved the bookmarks to an HTML file. You might consider making this a condition for the download. I do not like loosing all my bookmarks!

FEBE (Firefox Environment Backup Extension) {web link} FEBE allows you to quickly and easily backup your Firefox extensions, history, passwords, and more.
