Firefox will support Manifest v3. However Mozilla will be implementing Manifest 3 differently so the routes Ublock and other extensions use to maintain privacy and block ads will still be available. Firefox will support both the original route and the new limited option Google is forcing on Chromium.
Googles implementation deliberately locks out extensions by removing something called WebRequest, supposedly for security reasons but almost certainly actually for commercial reasons as they are not a neutral party. Google is a major ad and data broker.
Apple will apparently also be adopting the same approach for Safari as Mozilla is for Firefox.
