I just tested InterWeb, SpiderWeb and ArcticFox. I tried to post on AmigaWorld but the text and background are the same colour! That makes it near impossible to edit. I can only see it when drag selecting. I went into browser settings but they were limited with not much for colour. To my amazement a ten year old iBrowse is much more configurable in the palette department.

Is it because AW is old and lacks full on CSS? The AW gadgets are all black and inverted looking as well. It's hard to tell as I'm using Fienix right now and it has a black desktop theme.
It looks okay here though and the text looks normal with black on white.
