[Zotero 9] ChromeUtils.import(Console.jsm) has been removed and logs startup errors

[lwz20210407]

Summary

Easier Citation 0.5.4 uses the removed ChromeUtils.import() API in its bundled console helper. Zotero 9 records repeated errors during plugin startup.

Environment

• Zotero 9.0.6
• Easier Citation 0.5.4
• Windows 11

Actual result

ChromeUtils.import() has been removed. Use importESModule():
ChromeUtils.importESModule("resource://gre/modules/Console.sys.mjs");

The packaged chrome/content/scripts/index.js includes:

if (typeof globalThis.ChromeUtils?.import !== "undefined") {
  const { ConsoleAPI } =
    ChromeUtils.import("resource://gre/modules/Console.jsm");
}

On Zotero 9 the compatibility stub exists but throws, so the typeof guard does not prevent the error.

Expected result

The plugin should start without using removed Firefox/Zotero module-loading APIs.

Suggested fix

Switch to ChromeUtils.importESModule("resource://gre/modules/Console.sys.mjs"), or update the bundled toolkit/logger implementation to a Zotero 9-compatible version.
