Importing Bookmarks

Hi,

Im using FF portable 3.0.7, and the newest version (3.x) normally installed on HDD.

If i export the bookmarks normally as .json file from the HDD-FF, and then import them into the the portable one with Bookmarks-manager -> import -> restore... then after a restart the bookmarks are gone again.

Why is that? I found a posting here saying u can do it with the portable app suite, which i actually don't use right now, cause i only need like 3 PortableApps on my stick.

Whats the best way to do it? With the suite only?

regards,
