Don't be shy. Tell us what you think.
For your purposes, which are far more sophisticated than mine (or anything that I'll ever do), Firefox obviously presents downside issues. But for the things I do, it works wonderfully.
On the other hand and to my sensibilities, Safari well and truly sucks. I can't figure it out for the most part, and Pogue's dissertation on it doesn't provide sufficient assistance. But that's just me.
What's your take on Google's Chrome? Or are you, much as I, reluctant to engage given Google's information mining? A number of colleagues seem to like it, but I trust my judgement more than theirs.
