How am I being an asshole? The message I proposed is factually correct and, equally important, honest. Their current message "Oops... you're not using Chrome" is not recommended, IMO, as it triggers a negative response with some visitors. Btw, I've tested their tool in Firefox (by spoofing my UA string). From what I can see, it works fine. I recommend testing in Firefox, resolving any issues, and then, including Firefox in the list of supported browsers.
