How to make a background color transparent in Adobe Fireworks

Apply the Convert to Alpha filter. Filters > Other > Convert to Alpha.

I haven’t done enough playing around to know if this only works if your background color is the same as the color you want to make transparent, but it worked perfectly on my image:
