jQuery True "cross browser" beforeunload

[WolfShade]

Hello, everyone.

Trying to find a truly x-browser "beforeunload" event handler. I've tried this one, already:

It does not work in FF10.

Thank you,

You are not going to find one because that is not a part of the standards and so browsers do not have to implement it.

It is easy enough to disable it in any browser anyway since most uses for it are simply annoying and serve no useful purpose.
