Go to "The HTML5 Test".
Click on the "Other Browsers" tab.

1st - Google Chrome (I don't like it).
2nd - Maxthon (the interface isn't very customisable though).

We basically ignore Internet Explorer (even v10).
We are supposed to check our assignment site with Chrome & FF.
I've also installed Opera and Maxthon.

Some people in my class have Macs, so I guess they check with Safari too.

There are HTML5 tags that aren't supported by any browsers (yet).

Chrome, FF and Opera all support WebM (.webm).

Chrome, FF and Opera all support Ogg (.ogg).
IE and Safari will play Ogg using plugins.

I guess that MP4 (.mp4) is for Apple.
