Not selective but
The usual way is to export the firefox bookmarks as a .html file using
bookmarks -> manage -> file -> export
Then
Import into opera using file -> import and export -> import
netscape/firefox bookmarks....
Earlier I recommended BookmarkBridge. But it is all or nothing as to
merging bookmarks. You asked for selective merge.
Sorry for the unsuitable recommendation.
Good luck.
