A rejection with Blue Argon means that your package does not meet the requirements for Manifest V3 (MV3). Manifest (MV3) represents Google’s latest shift in Chrome extensions and it comes with tighter security and privacy controls and increased performance standards. Google is also stricter when it comes to the remote execution of code, handling of scripts, and bundling of external dependencies.
In short, extensions that get rejected due to Blue Argon are practicing disallowed code execution, most commonly the use of remote code scripts or unsafe execution methods.

All logic must be static, reviewed, and bundled inside the extension before submission.

It works in your dev environment, and when you submit it, once google reviews it, it gets rejected with Blue Argon. Why? Because MV3 will not allow external code sources. You would have to locally bundle Firebase libraries within your extension ZIP file and give them reference directly.
Blue Argon rejections can be frustrating for the developers. However, the fixes are usually simple once you understand MV3 rules and policies.
