Google's New Web Environment Integrity Proposal Dismissed by Brave, Mozilla, and Vivaldi
(news.itsfoss.com)
This is a most excellent place for technology news and articles.
No, safari is based on WebKit (which itself is based on KHTML from KDE). Chrome once upon a time was based on WebKit, but it's now based on a fork called blink.
In any case, this is more of a "will Apple implementation what Google wants implemented?" question. Same with Mozilla being in that list, they use a completely independent engine for Firefox that shares no lineage with Chrome.
Thanks
