1853412 - Set matchAboutBlank to false in scripting.registerContentScripts for webcompat

Status: RESOLVED FIXED

(WebExtensions :: General, task)

Description

[Rob Wu [:robwu]]

Until there is a better m-c fix (bug 1853409 / bug 1853411), we should set matchAboutBlank: true to false, at least for webcompat at https://searchfox.org/mozilla-central/rev/b741ddde6c678ca7025858952202d20664491555/toolkit/components/extensions/ExtensionScriptingStore.sys.mjs#182

This is needed to unblock bug 1853013.

Attachment: Bug 1853412 - Add an hidden pref for matchAboutBlank defaulting to false in scripting.registerContentScripts. r?robwu!

This patchs introduces an hidden pref named extensions.scripting.matchAboutBlankDefaultFalse,
it's only purpose is to more easily confirm if a bug reported to us for the scripting.registerContentScripts
API is due to the current default value set to true on the matchAboutBlank flag for all content scripts
registered through the scripting API.

Depends on D188354
