I've been using Chrome for the last 2 months, and today was told Firefox wasn't working with a wordpress blog I have to administer... since when does firefox have problems viewing things? I thought that was IE's job.
One thing he can try to get speed improvements is to absolutely position a double-width canvas tag in an iframe and move the entire canvas tag one pixel to left on each refresh. Then he can just paint the new data on the right-most visible pixel. One canvas has moved -width px, just do a .save() / .restore() and reset it to left: 0px.
I'm not certain if it will help for sure but I have an inkling it might.
It's also working near perfectly in Opera 10.61. (There is a bug initially, when the lines should start in the middle of the chart, rather than on the left)

I'm running it in chrome (on windows) on a not-great machine and it's taking 23-25% of one of the two cores.
