     "description": "Zstandard, or \"zstd\" (pronounced \"zee standard\"), is a data compression mechanism. This document describes the mechanism and registers a media type and content encoding to be used when transporting zstd-compressed content via Multipurpose Internet Mail Extensions (MIME). Despite use of the word \"standard\" as part of its name, readers are advised that this document is not an Internet Standards Track specification; it is being published for informational purposes only.",

-    "mozPositionDetail": "While we believe zstd is a promising technology, its use in a general-purpose web browser (given the existing slate of compression algorithms) has not been demonstrated to provide compelling new utility, and does not clearly warrant the additional maintenance cost and attack surface of adding such code. We are deferring a final position pending a more comprehensive and quantitative analysis of the benefits zstd would unlock on the web today - either dictionary-less, with static dictionaries, or with dynamic dictionaries. For either of the latter two options, we'd also need a credible plan for generating and delivering those dictionaries that aligns with our values.",

+    "mozPositionDetail": "Zstandard/Zstd has been shown to be an effective compression scheme especially for dynamic content, by reducing load on servers to deliver the same level of compression.   It also enables improvements from future work on Compression Dictionaries.  Chrome shipped support for Zstd in early 2024, and Firefox followed soon after.  It has been judged to be worth the ongoing cost in maintenance and complexity to support for decompression, and is also useful for supporting TLS certificate decompression.",
