Don't like Firefox :). Yeah, I know, I hear it all the time. I tried it (actually, it was Mozilla I tried, but still), didn't find anything special about it. Actually, it drove me crazy. Probably just me, though...
Oh, and much thanks for the answer. I shall try that when I get home.
Firefox isn't Mozilla. Yes, they're related, but the two are really different in terms of interface. I've switched a number of people to Firefox that didn't like the Mozilla suite. You really might want to give it a try.
I guess I wouldn't feel bad about using their wireless connection as long as they aren't being charged for the bandwidth that you are using and you don't expose them to some form of liability (illegal filesharing) or endanger their network with *virii.
