Firefox will not open any new sites that I have never been to before nor will it let me search for any questions that are new on the little search feature on the top right of the screen. All sites that have been previously visited are fine - for new ones I just get the little circle that goes round and round (sorry, I'm not really computer literate) until it finally tells me that it has timed out. I can get to these new sites just fine through explorer. I may remember incorrectly but not long ago there was an update for something (may have been java or google) and afterwards a box popped up and I think I checked something that I thought I was supposed to check but now think I wasn't - but have had this problem ever since.
