Option 1: Command-line download extension as zip and extract

extension_id=jifpbeccnghkjeaalbbjmodiffmgedin   # change this ID
curl -L -o "$extension_id.zip" "https://clients2.google.com/service/update2/crx?response=redirect&os=mac&arch=x86-64&nacl_arch=x86-64&prod=chromecrx&prodchannel=stable&prodversion=44.0.2403.130&x=id%3D$extension_id%26uc" 
unzip -d "$extension_id-source" "$extension_id.zip"

Thx to crxviewer for the magic download URL.

Option 2: Use the CRX Viewer website

Option 3: Use the CRX Viewer extension

The Chrome extension source viewer is open source (github repo) and makes this super easy.

Option 3: View source of locally installed extension

1. Find your Chrome local profile directory. Open chrome://version/ and find the "Profile Path:` field. Open that folder up.
2. Open the Extensions/ subfolder
3. All your extensions are here, with typically readable source.

Mapping between locally installed extension IDs and names

• On about:extensions, turn on Developer Mode and you'll see IDs under each entry
• Inside the Extensions/ folders, the manifest.json has a readable name field

Thanks! I used Option 4, it needs some work to find the correct folder, but if you just installed the plugin, just sort by folder modified date and pick the most recently modified one that is not Temp. By the way, Option 4 is incorrectly named "Option 3", so there are two "Option 3".

Thanks Paul!
