If you ever needed a reason to ditch Internet Explorer in favor of Mozilla Firefox (or even Opera), here is a great one as reported in the Washington Post:
For a total 284 days in 2006 (or more than nine months out of the year), exploit code for known, unpatched critical flaws in pre-IE7 versions of the browser was publicly available on the Internet. Likewise, there were at least 98 days last year in which no software fixes from Microsoft were available to fix IE flaws that criminals were actively using to steal personal and financial data from users.And what about Firefox, you ask?
In contrast, Internet Explorer's closest competitor in terms of market share -- Mozilla's Firefox browser -- experienced a single period lasting just nine days last year in which exploit code for a serious security hole was posted online before Mozilla shipped a patch to remedy the problem.Definitely read the rest of the article here, and take a look at this graphic, which helps illustrate the timeline very nicely.
