Older add-on does not appear in about:debugging#addons

I have Developer Edition installed (v51) and some add-on for Firefox, with maxVersion set to 41.0

I enabled unsigned add-on installation, and was able to install and use it.

However, it does not appear on about:debugging#addons , and basically I have no way to debug it.

How do I figure out the reason for that.

In fact, Browser Toolbox solved my problem: I can debug my extension using Browser Toolbox.

Hi   !
Find the add-on in   about:addons  (not   in   'about:debuging')   and click the debug button on that page.

The about:debugging page provides a single place from which you can attach the Firefox Developer Tools to a number of debugging targets. At the moment it supports two main sorts of targets: restartless add-ons and workers.

Hi, the-edmeister. The extension in question is not a restartless add-on, and not a worker. It is a xul add-on. If about:debugging does not allow to debug that kind of addons, is there any other way?

Ho Happy112,

I do not have a debug button for either of my addons on the about:addons page. Only a "Debug Add-ons" in the dropdown menu, that leads to about:debugging. However, at the page you provided, I found

The Add-on Debugger is not available for restart-required XUL overlay add-ons. To debug add-ons like that, use the Browser Toolbox instead.

I will try that.
