Brotli

Brotli is a compressed data format developed by Google. It is designed for a high compression ratio, and fast decompression. When used as a web content compression encoding, it uses  in the   header so that a browser can signal support; this support is present in newer versions of Firefox and Chrome as of early 2016.

While the addition of this format to Firefox/Mozilla was still under discussion, there was a bit of a mini-flap over earlier proposals to use "bro" as the encoding identifier (and file extension for Brotli-compressed files), as this was deemed by some to be misogynistic. After some debate over  vs. vs. , the shorter of these was ultimately adopted.
