Trying out 2.0 here, and it requires an installermodule. So it fired up Iceweasel, and I couldnt see which fields were which - I had to boot up chrome and load the page, just to see which field was email and which was promo code etc.
I think that the installer-module page should not use wordpress, it should use just a custom or old website specially designed for it, so that iceweasel works.
Is this fixed now? I have been working on that page recently, tell me if displays correctly otherwise I can try to remove more "new css3/html5 codes" that should be the cause
The best way to test with a non html5 browser and check if it renders stuff correctly is to open it with "netsurf".
I've got it installed for solely that reason.
