Where is Chrome Extension's Setting Files/Databases? I don't seem to find Chrome Extension's Setting Files/Databases in OSX, it is not in the extension folder aka ~/Library/Application Support/Google/Chrome/Default/Extensions.
~/Library/Application Support/Google/Chrome/Default/Extensions is for the static extension files only. Storage space for Extensions is found in ~/Library/Application Support/Google/Chrome/Default/Local Storage:
