1986078 - "The Web Developer Tools panel has crashed" when attempting to inspect extension

Status: RESOLVED WORKSFORME

(Thunderbird :: Add-Ons: General, defect)

Description

[Jonathan Kamens]

1. Open the add-ons manager.
2. Click the gear and select "Debug Add-ons".
3. Click the "Inspect" button next to an add-on.
4. Instead of the inspector window opening, you get a window which says "The Web Developer Tools panel has crashed."

Stack trace that appears in that window:

TypeError: can't access property Symbol.iterator, Startup.KeyShortcuts is undefined
Stacktrace
_addWindowHostShortcuts@resource://devtools/client/framework/toolbox.js:1388:24
_addChromeEventHandlerEvents@resource://devtools/client/framework/toolbox.js:1210:10
open@resource://devtools/client/framework/toolbox.js:1029:12

There's also at least one add-on (ToggleReplied) for which, when I click the Inspect button, the window doesn't even pop up. There is no error in the error console, the button just does nothing.

Yep, I can confirm exact same issue. This is preventing me from updating -- had to keep a downgraded parallel install for dev purposes

This is caused by devtools switching to moz-url://

I guess we need a similar fix as done in Bug 1986379

Can affected users confirm, that this is fixed on Beta 144 (by Bug 1986379), allowing us to close this as a dupe? I tested ToggleReplied and was able to properly inspect it.

I am no longer able to reproduce this in current TB beta.
