2008473 - Developer Tools Fail when clicking Inspect: JSProcessActorChild cannot send at the moment

Status: UNCONFIRMED

(DevTools :: General, defect)

Description

[Abdallah Elnady]

Steps to reproduce:

Unsure how this exactly happened, might be a one-time edge case, but it's still worth taking a look at. Happened When I Right-click + Inspect an element. Nothing is really unique about this element, just a normal paragraph element with average styling.

Error in Web Developer Tools:

Error: Protocol error (InvalidStateError): JSProcessActorChild.sendAsyncMessage: JSProcessActorChild cannot send at the moment from: server0.conn0.watcher3 (resource://devtools/server/connectors/js-process-actor/ContentProcessWatcherRegistry.sys.mjs:252:38)
