imo the new logo is an improvement, but it just seems a bit too simplistic, like 5 minutes in GIMP simplistic...

making logos simple isn't always bad, the EFF logo looks alright, but if you are adding gradients and shadows you should add more detail than a just a circle, something like the firefox quantum logo would be amazing.

tbh the black and white version of the old logo, without any ugly 2005 style gradients looks better than this.
