Sage Firefox problem

hello everyone!

i have a problem with sage extension for firefox 2.0 portable. every time i run ffp the feeds in sage automatically update. in sage preferences i removed this option. and also noticed that it uses the enitre ffp cache. i also removed the ffp's "clear cache on exit" function - in order to let sage save the feeds content (in order to be able to read them offline) - but unfortunately no chanegs. i have no ideas what to do. also observed several forums but found nothing. pls help me.
