More than likely all the gecko based browsers will be vulnerable to this.
So that would include Mozilla, Camino, SeaMonkey... possibly even things
like Thunderbird if you could get it to render.

Nice find guys!

Firefox 2.0.0.11 File Focus Stealing vulnerability:

Sorry Mozilla, but the recent file focus fix was not enough. I think
Mozilla made another mistake while fixing the previous file/label
issue. Because now I embed a file field and a textfield inside one
label. When this happens, and you type only one time in the textfield,
the focus travels to the file field and the value travels with it.
Back to the drawing board I would say. I only got it to work in
Firefox, Gareth checked Safari for me, and it also works in Safari. I
guess this type of exploit could function on other HTML objects as
well, and could be very dangerous because it only requires a one time
focus in a textfield.
