unfortunately, our ageing selenium scripts do not work on anything but firefox. Again I want to stress that Aurora works really well on most everything. I personally prefer Firefox to other browsers. But that doesn't mean that FF is perfect... nothing is.
I don't think anobody stated that Firefox is the perfect browser. Each browser has its strenghs and weaknesses but I am more keen to accept flaws on a browser that's opened by nature: that's why I have always been using Firefox, even when in term of performance it was way behind Chrome. Today I am happy that Firefox has caught up and is even doing much better in some area.
