1816579 - ReadableStream cannot be constructed in content scripts

Status: RESOLVED DUPLICATE of bug 1757836

(WebExtensions :: Untriaged, defect)

Description

[elias.holzmann]

Attachment: extension_readable_stream_bug_reproduction.zip

Steps to reproduce:

• Install the attached web extension (contains a content script constructing a ReadableStream and logging it)
• Visit any web page (not internal pages and not AMO so that content scripts aren't blocked)
• Open Browser Console (Ctrl+Shift+J), switch to multiprocess mode (for reasons unclear to me, the error message is not shown in the web console)
• Give permission to run content script on the current page

Actual results:

Error: Permission denied to access property "autoAllocateChunkSize"

Expected results:

The result of "new ReadableStream({})" should be logged, i.e.

ReadableStream { locked: false }
