I have convinced my friend to use PortableApps on his flash drive. Since its install he has had a continuous problem with Firefox. Almost every time he opens his web browser it does not show his bookmarks and I have to re-name the places.sqlite. I am then able to restore his bookmarks then everything is fine, until he closes the browser and it will start all over. I have tried removing Firefox and installing it but nothing is different. This is strange since I haven't had one issue with mine. He now has version 3.0.3 and it still acts the same. I hope someone knows what is going on and what can be done to fix.
