Websites like stackoverflow, ask.mozilla.org won't show new comments until i press F5
I just installed new os, downloaded firefox and now when I go to sites I used to freuqntly visi tI'm seeing an odd behavior. New comments people post are not shown on browser restore (i have restore all tabs as startup setting) or when i visit the page. I have to go to the page and hit f5. Is my only option to go to IE and set "Force check for new changes on website everytime?" I was hoping firefox would be completely independent of IE settings.
