Get Turnabout: “Turnabout is a plugin for Internet Explorer that runs user scripts of your choice on any website. User scripts are like plugins for websites. They can enhance your web experience in a lot of ways… Essentially, Turnabout does for IE what Greasemonkey does for Firefox.”

Turnabout is another implementation of the GreaseMonkey concept for IE. Compared with Trixie, it has several advantages. The developer includes source code and permission to modify and distribute the source code and binaries. In addition, the plugin has no external dependencies on .Net or anything else, so the required download size is small.

The downside appears to be that fewer working user scripts are included with the product, but that appears to be primarily a licensing issue that will get worked out over time.

UPDATE: The author of Trixie has decided to throw in the towel in deference to Turnabout. Even if you’re a Firefox fan, as I am, it’s reassuring to know that Greasemonkey innovations have at least the potential of being accessible to anyone regardless of browser choice.
