The backup and restore function requires that one has a file called system/midori/config-backup present. You can just make a copy of system/midori/config file. However, if you have already started the files from post #10 the backup has been done with an empty file which means that midori doesn`t know where to store downloads etc.
Therefore have attached a "clean" config-backup file to post #10. Just copy this file into system/midori/. After that you will have to redo the settings of the font size just once more but then it will be stored forever.
Alternatively just add this line
Code:
download-folder=/mnt/ext1
to the config-backup or select this settings in the preferences of midori.
