Re: FFS?
Of course it's important - to him. Other things are important to you. Other things are important to me.
One thing we can all agree on, I think, is that diversity is good. Choice is good. Having one browser on top is inevitable, but other browsers must exist to keep things fair.
For me, I do not mind at all that Firefox is not on top. Being on top makes you the prime target for all the nasties. Being obscure makes you uninteresting to the nasties. I will stay with Firefox as long as NoScript keeps on working. Firefox and NoScript are my preferred way of browsing and I will only change the day I have to.
