Thank you for this interesting link, enabling comnparison of browsers. Safari seems quite vulnerable, although only from 5 advisories. If you're using Mac OS X Camino is a good bet with none, as is Opera. Both are very pleasant browsers to use. Firefox seems to work for most sites, as does Safari. I can usually get into any site with at least one of these.Another interesting comparison would be how various OSs stand up to malicious attack. Mac OS X is reputedly quite secure. The more open source something is the more likely it is to be sound, as more people have a chance to check it out and make sensble changes. By that argument Linux must be even more secure. Any comments?It always occurs to me, and it has arisen in this discussion, that people often use a system because it is there, and maybe do not even have the opportunity to compare it with another. Time and workplace are two main constraints on our choice of computer. Also these points only matter a lot if you spend a lot of time using the computer.
