IE is THE worst browsing utility hands down.
Download Firefox @ www.Mozilla.org. It will download the most current version by default, 4.0 something, and if you have issues with that version, as I did, you can install previous versions.
The new version did not support any of the extensions I use and Flashblock is absolutely an essential one for me.
I’m running firefox 4.0.1 with the Flashblock 1.5.14.2 addon.
No problems.
