I highly doubt that they'll list it - I can't find any Mozilla page promoting a third-party tool anywhere. You're free to try, of course (and I'd be very grateful if you succeed).

@hbenl ok, I'll ask. Do you know any similar debugging tools that use Firefox's remote debugging prototol? The more plugins, the more likely they'll add a page. AFAIK even Intellij does not support this:

Due to the recent crucial changes in the Firefox architecture, neither remote debugging nor standard for IntelliJ IDEA local debugging work for Firefox. This procedure is a temporary solution and is applicable to Firefox versions 33, 34, and 35.

The only one I know is the other debug adapter for VS Code (which was started by a Mozilla developer "to quickly add basic debugger support to be more comfortable with vscode" and hasn't been updated since its initial release 2 months ago).

I've created https://bugzilla.mozilla.org/show_bug.cgi?id=1299111 for this. Let's see :)

I am sure they have nothing against adding it there. Just wonder why so few IDEs support it. AFAIK it is even nearly the same protocol as Chrome/ium uses.

AFAIK it is even nearly the same protocol as Chrome/ium uses.

Not really - there are some basic structural similarities between the two protocols, but when you look at the details, they're quite different.

Just wonder why so few IDEs support it.

The good news is that VS Code's Debug Adapter Protocol seems to become a standard for IDEs (like the Language Server Protocol already did). AFAIK Eclipse and Visual Studio are working on supporting this protocol soon and I think that others will follow.
Then I will be able to offer this adapter for these IDEs.

Will be handled in #108
