SaganIZER is an extension for Google Chrome and Mozilla Firefox created for the Carl Sagan Day 2014. What this extension does: Replaces all images with random Carl Sagan images. Replaces the word "God" by "Sagan". What this extension doesn't does: A coffee. A vortex. Pseudoscience. A Spacetime Odyssey. Okay, I will try to be seriously. saganIZER is an extension that replaces all images from all websites with random Carl Sagan images. This extension also replaces the word "God" (case-insensitive) by "Sagan" (in short is the same thing).
