As mentioned in the title, you really need to remove the rainbow macbook background image in your documentation page. It’s so damn hard to read the words because of it. Very infuriating.
@ben, I had a look…
Where is this rainbow macBook background?..
Sorry that looks like a firefox regression, we fixed Sparkle for the next update and republished the documentation. Please get in touch via email if you urgently need a fix for this.
