anyone know how to debug chrome extention independently (not using google chrome)

[DominicCummings]

Why do you have to be not in google chrome? What happens if you toggle on debug mode -- https://developer.chrome.com/docs/extensions/mv3/tut_debugging/? If it detects dev tools there are workarounds (for anti-anti-debugging). What about Chrome's extension source viewer? (link: https://chrome.google.com/webstore/detail/chrome-extension-source-v/jifpbeccnghkjeaalbbjmodiffmgedin)

I understand that to use it you:

• Click on the yellow CRX button, and choose "Download"
• Extract the zip file.
• Read the source code, and change it.
• Visit chrome://extensions/
•  Enable Developer mode, by activating the switch in the upper-right corner.
•  Click on the "Load unpacked extension" button.
•  Select the folder of your extension (there should be a manifest.json).
• Confirm, and load the modded one. That should let you get by anti-anti-debug if present.
