The Canvas Debugger is one of our less popular features. But it is also not maintained, and not new features have been added in a while, while bugs and intermittents _do_ happen from time to time. Additionally, it is built with XUL and it's hard to find people who are proficient on it in order to keep working on it. This bug is to track: - potential alternatives in the form of a WebExtension - migration paths for panel users

This one is a bit hard to find, but this needs to be removed too: https://searchfox.org/mozilla-central/rev/5053031ba7621fa8f63f42de4c204ab3561e4e59/devtools/client/themes/toolbars.css#189 :)

Why was the Canvas debugger silently removed without any warning????
I've just run into an issue with my 2D canvas drawing context code that I needed the canvas inspector for, and I'm just spent 1/2 hour trying to find it - only to run into this bug.
Spector.js is suggested as an alternative (link: https://addons.mozilla.org/en-US/firefox/addon/spector-js/#&gid=1&pid=2), but as far as I can tell it's only for WebGL contexts, which I'm not using (I'm using a 2D drawing context instead).
Does anyone know at least of an alternative to this? It was an essential feature that I used regularly when developing canvas-based applications.
I haven't done any canvas-based development for a while because of other University work pressures, but now that I'm back to it I'm shocked and rather disappointed.
Okay, and now there's no Spector.js (which is also useless to me for debugging 2d canvas context) nor Canvas Debugger. Nice.
