Chrome-like extensions in Internet Explorer?

I have an idea for an extension that I would like to try to implement across all of the major browsers. Currently Chrome, Opera, and Safari all implement extensions more or less the same way (HTML and Javascript... basically a pseudo web page), and Firefox is capable of emulating this.

That leaves the "old reliable" Internet Explorer to deal with. Is it possible to implement an extension in it that can act akin to how extensions act in Chrome, Opera, and Safari? I would 开发者_Go百科want as identical an experience as possible across all the browsers.

Use Chrome Frame, it will cover Google Chrome and Internet explorer.
