Probably still gonna stick with Safari for day to day stuff, but for development, Firefox Developer Edition is pretty fucking sweet.
Performance is pretty good and it comes with a host of tools (it can debug animations?? WHAT??) that make very useful while I'm building.
It's been awhile since I used a dedicated browser for development work, but FDE is really useful specifically for that task.
Social is the primary social media platform for the forth coming fourth version of Play Vicious, a new initiative built to bring attention to the plethora of creative acts that don't get the shine they deserve.
