Add-Ons Cause 70 Percent of IE8's Crashes

Microsoft whitepaper:

"Add-ons cause most browser crashes, accounting for over 70 percent of Internet Explorer 8's crashes. Slowdowns in Internet Explorer 8 are very often caused by add-ons-especially when you open a new browser window or tab."

 

A large segment of users don't pay attention to what's being installed on their computers. The end result: Every app they install ends up leaving on another clumsy piece of garbage code to Internet Explorer.
 

So there's more toolbar than browser -- and all those add-ons fighting for control over searches and trying to load "valuable" contextual data Causing IE Crash.
