Tell you what, instead of ripping into you which was my first reaction ( bad ) how about you prove your case.
Tell me how much harder it is to adapt plugin code from another platform/browser to this platform/browser combination vs porting Mozilla and then the plugin code.
Note that you are conversing with someone who has ported Mozilla before onto two platforms.
I dont think AmigaOS needs Mozilla, I think it needs a *better* browser than all the other platforms - the Amiga edge. With Mozilla there is no value add to using AOS.
