It says it about itself:
This is a simple program to save and restore, bookmarks, passwords, cookies and ad blocking information. The program is limited to backing up only one profile. I created this program to fill the gap left by MozBackup, since it was created just for Windows users. I also created it to provide an open version. (Uses: wxPython 184.108.40.206)
There might be some options to parse the backup, insert the password information from galeon and re-insert the information back into firefox. Exercise left for the reader.
