Starting with the #LibreWolf v148.0.2-2 release, we've begun to include an experimental ARM64 build for Windows.
We'd be thankful for feedback from anyone who'd be adventurous enough to help us out and try it! :)
(It should be emphasized again that this ARM64 release for Windows is experimental and potentially unstable, and should be treated as such!)
