Hmmmm... I got some kind of issue with FireFox 1.0PR. I am not able to find out how I can force it to revisit the page everytime I visit the URL. I am thinking of a solution: to set the cache on 0, put I guess this is not the one I am looking for. In Mozilla this is quiet simple: Edit -> Preferences -> Advanced -> Cache. But where is it in FireFox? Update: As you may expect setting the cache to 0 is an option, but not the best. Maybe I wasn't clear enough: I am looking for an option "Revisit/Check page every time". However thanks to Neel and Anonymous.
