About the Name
This project drives an important part of Firefox's "felt experience". That is, the feeling of using Firefox, hopefully in a delightful way. The word "felt" in this phrase refers to feeling, but it can be punned to refer to the textile. Felt is often made of wool, and Merino wool (from Merino sheep) produces exceptionally smooth felt.
