I had this error on my PC for ages, but never wanted to investigate as I use Chrome at work. However, a user phoned in saying that her’s is doing the exact same thing. I tried re-installing Internet Explorer 8, but this made no difference.

Example: “When I open a new tab, it crashes.”

Resolution: While there may be a handful of reasons that cause this to happen, there’s one very well-defined correlation between the IE Developer Toolbar and new tabs crashing. Simply go to Tools > Manage Add-ons and disable anything Developer Toolbar-related.
