Custom cursor using Javascript in Firefox

[rnd me]

Is .cur a proprietary M$ format that only IE supports?

yes and no.

.cur is basically a monochrome bitmap, so it may be viewable when loaded as a bmp, which many browsers handle.
Firefox allows .cur since 2.0

according to MDC, this is your best bet:

cursor:  url(foo.cur), url([url]http://www.example.com/bar.gif[/url]), auto;

Thanks for all your help, acoder's solution of adding the defualt afterwards works. Adding the url(***.cur) stopped working in IE but when I added the default it worked again in IE and now works in Firefox.

Many thanks all,

I now have it working in IE, Firefox, Safari and Google Chrome. Any ideas how to get it working in Opera?

I don't think Opera supports custom cursors.
