Its not necessarily always validation logic that I want to insert, sometimes its opening or closing a window, or refereshing a window, or making an asychronous request.

just because it's called a validator it doesn't necessarily have to do validation. you can call your method and do the "asynchronous" call you want to do.

I haven't used validators very much, only tried them a few times, does the javascript that they produce run in firefox?

I don't know. You're the one how needs to "hijack" the page to do "asynchronous" calls not me.

BTW, does talking like this pay more?

Have you played with Remote Scripting techniques at all? It might be a bit cleaner to do what you're talking about than posting back (as seems to be the preferred ASP.NET way of doing things). Remote Scripting allows you to create very tight, interactive, UIs (think GMail; no postbacks, no page refreshes -- responsiveness feels almost like a thick client).

Here are a few links of interest:
