Verified fixed with Firefox 117.0a1 (2023-07-26) on macOS 12 and macOS 13 arm. The history alone can be successfully imported from Safari after granting the Safari folder read permissions on a new macOS profile. I also filled in a new issue (bug 1845514) that history cannot be imported from Safari (see comment 8) if the Safari browser was never closed before for awareness.
