1930334 - Implement background.preferred_environment

Status: RESOLVED FIXED

(WebExtensions :: General, enhancement, P5)

Description

[Carlos]

As discussed https://github.com/w3c/webextensions/issues/282#issuecomment-2323428037

background.preferred_environment allows webExtension authors to specify what the background environment they prefer. This allows specifying both a "service_worker" and "document" environment while using the "document" environment in browsers supporting it (Like Mozilla Firefox and Safari).

Ideally this is supported right from the start when Firefox adds support for service_worker.

This has already been implemented in WebKit and available since Safari 18.
