"prefs.js" is a file in the subfolder of ~/.mozilla/abrowser (that is a  
folder "abrowser" in the hidden folder ".mozilla" in your home folder) that  
relates to your profile. There usually is the sole default profile, with a  
randomly generated prefix.

To only import/export bookmarks, display all bookmarks (either from the  
"bookmark" menu of the Web browser or using Ctrl+Shift+O) and click on the  
related menu.
