It is always interesting for me, as someone who is colorblind (Protanopia), to see these. I always have to call my wife in and ask if the images look different. She is always amazed that I can't tell the difference.
The original image and the Protanopia image are exactly the same to me.
The Deuteranopi looks very slightly different -- if I really stare at it. The other do indeed look different.
This is really interesting to hear. I am also red-green colorblind (Protanopia) but the difference between the normal and Protanopia images here is very noticeable to me. I can see that red is missing in the Protanopia version.
I definitely have trouble with many shades of some colors, especially if the colors are really small on the screen.
So many Protanopia colorblind filters in games and apps mess up the colors way too much for me, and look worse and less visible than the non-colorblind normal color settings. Definitely interesting to hear about other colorblind users' accessibility issues.
There are so many degrees of colorblindness that accessibility is difficult to cover for all of us. I hope Mozilla and other developers are accounting for common colorblindness and testing with real colorblind people.

Facebook's ErrorUtils have recently been updated to use `window.performance.memory`, which is undefined in Firefox and causing an error to be thrown. This value is defined in Chrome. Looks like this was tested in Chrome but not in Firefox.

The book looks great, but being a startup, the price is hard to swallow for 20+ engineers.
