Well, I like the clean simplicity of the Chrome UI, and a lot of the stuff I do is Google related.
So, I did manage to get WebGL to work. The wording of the WebGL flag is kind of odd:
So to enable the disabling of WebGL you would click Enable. Hmmm, ok.
I noticed it when I did chrome://version and it showed the various command-line parameters that were enabled, and one said "--disable-webgl". By clicking Enable under flags I was actually disabling WebGL.
So, TurboTax says:
"Please make sure your computer meets the TurboTax Online system requirements.
To ensure you have the best possible experience using TurboTax Online, your computer must meet the system requirements below."
Actually not true, and one of my pet peeves with some web developers. I'll decide if it's working for me, thank you very much.
The user string says:
"Chromium 17.0.963.46 (Developer Build 0)
Which probably explains TurboTax complaining:
"Using a BETA or development version of a browser or operating system?"
Anyway, it seems to have all come together, and my taxes are done (from Windows). And other websites that doesn't like my OS can bite me.
