Is "-moz-box-shadow" supported by Firefox / Gecko only recently?

How well is -moz-box-shadow supported by Firefox? I thought I heard of it for quite some time but the page

https://developer.mozilla.org/en/css/-moz-box-shadow

says that it is not supported until Fire开发者_如何学JAVAfox 3.5 and Gecko 1.9.1? (with current Firefox 3.6.12 and Gecko 1.9.2) So it is not supported until recently, is that true?

That really depends on your definition of recent. Firefox 3.5 was released on June 30, 2009. It's also the oldest browser supported by Mozilla (has not reached end of life yet, but probably will shortly after Firefox 4 is released).
