Curious to confuse the Daily Mail with a newspaper. In my opinion its more an opinion paper written for middle class outraged of surbubia. Makes a change from their hoodie obsession pieces. Article had all hallmarks of being half researched. Avoid the tabloids if you seek truth and well reasearched articles
Like others I've use Firefox since its beginnings pretty much. Its far superior to IE in just its customization alone...you make it what you want (assuming someone has created the right add-on(!)). Faster too. Plus reading replies Microsoft have preprogrammed people to prefer the IE layout cos that's what the vast majority of people are use to seeing as it come bundled with Windows. Change doesn't come easy and it took me a while to warm to Firefox, its 100 times better in my opinion.
However the more popular it becomes the less secure it will be as hackers will adapt their attacks more to firefox as more people use it....the open source nature of it could be its undoing. So sush don't tell anyone about it and stick to old faithfull IE
