The Chrome extension source viewer is open source (github repo) and makes this super easy.
- Find your Chrome local profile directory. Open chrome://version/ and find the "Profile Path:` field. Open that folder up. - Open the Extensions/ subfolder - All your extensions are here, with typically readable source.
- On about:extensions , turn on Developer Mode and you'll see IDs under each entry - Inside the Extensions/ folders, the manifest.json has a readablename field
