I've decided to replace all the icons for my Mozilla browser installs with the icon from Netscape Navigator in a fit of nostalgia. Technically, it's not completely a falsehood, kinda.
If you want to as well:
- Download this icon: firefox.icns
- Right click your browser and Show Package Contents
- Go to ./Contents/Resources
- Replace firefox.icon with the downloaded icon
You might need to remove your browser from the dock and add it again for the changes to show.
First browser I ever used was Netscape Navigator Gold two point something, in primary school year five. Lots of numbers in that sentence.
