is there any instrument to get it vertebrae?
Answers: I've restored mine a couple times before. Go to the Bookmarks menu and select Organize Bookmarks, later File/Import, then select "From File". With WinXP, my backup were within
<Drive Letter>:\Documents and Settings\<User Name Here>\Application Data\Mozilla\Firefox\Profiles\ ou09ww4b.default \bookmarkbackups.
find the site and bookmark it again
