Are the firefox designers popping a lot of pills lately?!
This looks terrible. These enormous rounded corners are so disruptive, wastes so much space by making it necessary to constantly bump things out of the grid. I can see literally no utility in this whatsoever.
And why are there random clock icons all over everything?! This is not good information design. You seem to be just copying random features from infantile, annoying smart-phone apps and pasting them into a _desktop application_ which has a long (boring sure, but basically usable) tradition of interface culture.
Perhaps I'm showing my age, but it just feels like a desperate grasp at some kind of faux-naive, awkward chic that will be out of style in 6 weeks.
But I guess "form follows function" has now become "form follows cheap novelty marketing". Pfft.
