I’d love for us to add this too! Thanks for starting the discussion.
We actually have had this on file for years here : https://bugzilla.mozilla.org/show_bug.cgi?id=1031585 (and here too: https://bugzilla.mozilla.org/show_bug.cgi?id=1602648)
But knowing how laser focused we need to be (being a small team), it has never scored high enough on the importance scale that we got to dedicate time to do it.
In order to help move it forward, it would be awesome to start a discussion here with people around the following topics:
- Why do you need this tool / what problems are you trying to solve with this tool?
- Are there any problems with how Chrome DevTools does it?
