@abeisgoat investigated this, I’ll summarize what he told me.

It turns out this is only an issue with the standalone Firebase Tools binary (installed via curl) and not an issue with the npm install. So if this is essential to you, install firebase-tools via npm install -g firebase-tools and it should work.

The reason this does not work is because we use pkg to embed node inside the standalone binary. For security reasons this embedded node install blocks all Node debugging via the --inspect flag. We may be able to find a way around this, but it will be a pretty big change so it’s not likely to happen very soon.
