Please copy and paste the following code and view it in FF3. Under FF2 it looks normal, as with IE 7 and SeaMonkey, but the font is far too big in FF3. I use this code quite extensively. Web Plus X2 also produces the same font size whenever it cannot display a file in an iframe.

Reproducible: Always

Steps to Reproduce:
1. Cut and paste above script
2. load .html file into FF3
3. observe the text and play with the Factoriser to see the results.
Actual Results:  
The font for the end result is large and unsightly.

Expected Results:  
The font should be normal size. If this helps I modified the code to make it work as it should.
