Firefox, Seamonkey, and Google-Chrome all run as user spot. User spot can
only write in a few places, one of these is the Downloads folder
on the desktop. If you want to save something from Seamonkey /
Firefox send it to the Downloads folder. Each time the
browser is opened, the files in Downloads folder are changed to
owner spot. So if you need to import bookmarks to the browser,
place the bookmarks file in the Downloads folder before you open
the browser. Then open the browser and import the file.
Firefox and these other applications which access the Internet
run as user spot for security reasons, some see this as being
overly cautious. If you want Firefox to run as user root and be able to write anywhere, edit
/usr/share/applications/Firefox.desktop (right click and choose
Open as Text). Change the line Exec=firefox-spot
to Exec=firefox
(or seamonkey, google-chrome, etc) and save.
Or alternatively, if you want to convert all of these applications to
run as root, open the Control Panel, click the "System" tab ("Desktop" tab on older Fatdogs), and
you will find an applet called "Convert Spot Apps to Root Apps", and that will do the job.
