I'm having a strange problem with Firefox and Ubuntu on my notebook computer. Since yesterday, I've been getting the message "The connection was refused when attempting to contact ___", for some addresses including www.yahoo.com and www.google.com. Others, incuding slashdot.org, www.hclib.org, and www.newegg.com, appear to work OK. When I run the same computer with Knoppix, I can access yahoo and google. I have the same problem -- can access some sites and not others -- with the KDE Konqueror browser. So I think the problem must be some security setting in Ubuntu that I've inadverently changed. I'm not sure where to look, and I can't get to Google to look for clues. Does anyone have any suggestions, or can someone tell me in which files to look for what's blocking some web sites?
