Pixel Size and resolution

I can't believe FF has been out for close to 6 years now, and still does not treat pixel size and resolution as the rest of the graphics industry does.

Why can't the pixel size go larger than 600X600? I type in 2000, but it still renders it as 600X600 pixels! That is nonsense.

Resolution usually refers to dpi (dots per inch, or pixels per inch). It relates back to print media. Some printers can print up to 2400 dpi. So if you wanted an image to be very crisp and sharp (especially text on a large image) you would adjust your image to the sharpest resolution necessary for your image. This means an image of 600X600 at 300 dpi is essentially 18,000 X 18,000 pixels at 75dpi (screen resolution).

But from what I can tell FF does not have the capability to increase resolution or pixel width and height. What am I missing????

I will also add to what Rick has already pointed out is uncheck the "Reduce Preview Size" to see what your image looks like before rendering.....

In addition to the above replies I'd like to note Filter Forge is not designed for pre-print. It doesn't read the DPI setting that may be saved in your image file.
