I'm trying to import bookmarks from Firefox to Opera, searched the net and its supposedly saved in bookmarks.html at C:\Program Files\Mozilla Firefox\defaults\profile, but that doesn't seem to be it. Can anyone help?

If you go into bookmarks, and manage bookmarks, go to file, and you can export your bookmarks. Im pretty sure this exports them as a .html file - you choose the location. Then you can do whatever you want with the file...

Yeh I got that far, but the bookmarks.html file doesn't contain all my Firefox bookmarks

Think you have to select them all first...

Ok worked it out: In Firefox's Bookmarks Manager, export the bookmarks, then import it back into Opera - simple
