Firefox has one problem : The rights management within the program needs to be (over)worked.
The thing is that - as I read - Chrome (the engine, more or less) is allowed to do anything, the layer above it not. It's basically like in IEX. Now, if you find a way to Chrome, you can gain more rights than you houzld be allowed to have ... and there ARE ways, as I read. In that respect, Firefox isn't as secure as IEX, as I read in a magazine, at least in some points. That's partly cause by the false feeling of safety, because Firefox wasn't so much spread up to now.
Nevertheless, I use Firefox - and have an installation of Opera nearby. <img src="/ubbthreads/images/graemlins/winkwink.gif" alt="" />
The most safe way of surfing would be using Linux in conjunction with the text-only browser "Lynx". <img src="/ubbthreads/images/graemlins/winkwink.gif" alt="" />
