Someone suggested Opera. Surely as more and more people use it and it has a bigger market share more holes will then be discovered there aswell.
It is inevitable that software will have bugs in it - it is how the people responsible get on and fix them that is important. In that sense Firefox seems to be slighlty better/faster than MS at the moment.
Has anyone made a 'The Register' extension yet to help make pages readable by stripping out the overpowering ads?
