Do you know? Well, you can find out by running the Browser Security Test. I just ran the test (with all options) on Firefox 1.0, my default browser, and on Internet Explorer 6.0 SP2. What are the results? Both of them passed the test with 0 volnerabilities. That’s good. However, if you’re not sure which version of IE you’re running, I would recommend running the test. Plus, if you want more security in the future, consider switching to Firefox. That’s my advice, plus, you’ll love it.
