Hello Vincent,

I think you forgot to link to the bug that covers that work, if I'm correct this is https://bugzilla.mozilla.org/show_bug.cgi?id=1858562

I also filed a DevTools bug so we can investigate the impact this API might have on the toolbox: https://bugzilla.mozilla.org/show_bug.cgi?id=1997100
