> “As of today, from the major web browser vendors only Firefox offers defenses. Since uBlock version 1.25 under Firefox, the extension dynamically resolves hosts and sanitizes such requests if a match is found. Such a measure does not work under Chrome because this web browser does not offer a way for extensions to dynamically resolve hostnames.”
I assume he meant uBlock Origin (rather than uBlock) as it introduced uncloaking of CNAME requests as of version 1.25.0 for Firefox: https://github.com/gorhill/uBlock/releases/tag/1.25.0 https://github.com/gorhill/uBlock/releases/tag/1.25.0 .
