I've been using FF for a few months now and have enjoyed it. I use the tabbed browsing mostly. MS has been so reluctant to apply widely accepted w3c standards for reasons I don't understand. I still program my web sites to work equally in IE and FF becaue they have such broad usage. FF development as OS has nothing to do with security or blackhat/whitehat (what does that have to do w/ this I dont know).

I do know that when a security flaw was found in FF a couple months back, within HOURS there was a patch. We have to wait til a Tuesday once a month for MS to patch IE.

I personally don't see why there needs to be a war or exclusions over a browser. Both browsers are free so how can there be any profit?
