Woofie, my prejudice against FF is totally unfounded. I don't care for Yahoo, and since FF is somehow associated with Yahoo, I 'think' I wouldn't like it either. I also don't have it on my computer so it would take additional effort on my part to download and try it out. I'm essentially lazy...
I'm trying out Chrome and it seems OK. Everything takes some tweaking and getting used to and I'm slowly figuring it out without giving it a lot of thought (there's that lazy thing again).
I use Bing for my default search engine simply because I like the changing daily photos.
