The researchers tracked three browsers (MSIE, Firefox, Opera) in 2004 and counted which days they were "known unsafe." Their definition of "known unsafe": a remotely exploitable security vulnerability had been publicly announced and no patch was yet available.
MSIE was 98% unsafe. There were only 7 days in 2004 without an unpatched publicly disclosed security hole.
This underestimates the risk, because it doesn't count vulnerabilities known to the bad guys but not publicly disclosed (and it's foolish to think that such things don't exist). So the "98% unsafe" figure for MSIE is generous, and the situation might be even worse.
And one of the commenters flags up my particular beef with IE...
IE also sucks because it has its own particular, frustrating, and often incomprehensible ways of rendering code. Anyone who has tried to design a site for several browsers will know what I mean.
While that may not seem like a security issue straight off, I would submit that having to add a lot of complexity and workarounds reduces security. Also, lack of compatibility can constrain people's ability to use more secure browsers.
Quite so. Add in the fact that IE for the Mac rendered code completely differently to IE for PC and you've got even more of a nightmare.
So, would the 54%, or so, of people who view this site using Internet Explorer, please not do so? You'll find Firefox links at the top of my right sidebar. If everyone dumped IE, they would be doing me (and all web developers) a favour, they would bring down the cost of website development and they will save themselves a whole host of security problems.
fixed image(which is often usefully used to make divs appear translucent) would be used a lot more. Websites could, much more easily, be really beautiful...
So, please, for your sake as well as ours: get rid of IE.
