Yes, it seems that browsers are back in wild times when technology couldn't wait for standards and everything was implemented differently.
When i open Mozilla Webgl demos with Safari (https://demos.mozilla.org/en-US/ - check it out, there are wounderful things created with webgl), it says: your browser does not support WebGL. To view any of the demos tagged with WebGL, please install an up-to-date web browser (Firefox 4 or Chrome 9) and up to date video card drivers.
Btw, i've tricked easypano Safari detection to see if firefox4 displays easypano html5 panoramas and... it doesn't (displays something, but that's not panorama).
So much for now - we'll have to wait for the better times.
