I personally believe that your keen plea in favour of Opera nearly resembles an ad: that's not a problem for me, and I'm sure it has its advantages. OTOH I'm not the kind of guy that takes a browser as a religion (I make fun of those who make up conflicting camps in a IE-FF flame) but one's best tool is the one she's already used to. And FF is mine. I'm at ease with it for quite about everything but possibly these recent difficulties with keyboard navigation. Not to mention that I had tried Opera some years ago, and I wasn't that enthusiast about it: I may retry it now, for fun. But I'm not leaving FF and the useful plugins (and some subtle customization) that make my experience of it even better...
