For sandboxing webapps you will need to install these optional dependencies: wasi-libc lld wasi-compiler-rt wasi-libc++ See https://hacks.mozilla.org/2020/02/securing-firefox-with-webassembly/ to learn why you might want to enable this feature. A different approach, https://wiki.gentoo.org/wiki/Simple_sandbox , can be implemented without any additional dependencies. If you compile firefox frequently, consider installing ccache and sccache, so that later updates can use the artifacts left over from previous builds.
