Get-ChromiumExtensions

Description​

Gather information about extensions installed on Chromium browsers for each user.
Supported Browsers: Google Chrome, Brave, Microsoft Edge Chromium

Requirements​

  • Run as administrator
  • PowerShell v5+

Usage​

  1. Get valid user profile paths.
  2. Set the UserProfile's relative path to the 'Extensions' directory for each browser.
  3. For each browser's 'Extensions' directory for each user profile, perform the following steps:
    1. Find the installation path and Manifest.json file of each installed extension.
    2. Read the Manifest.json file to find the name of the extension.
    3. The manifest file either contains the name of the extension or the reference of the variable storing the name in the messages.json file.
    4. If the manifest file returns a variable starting with double underscores (e.g., __MSG_APP_NAME__), then attempt to find the extension's name from the 'en/messages.json' file followed by the 'en_us/messages.json' file.
      For example, if the name stored in the Manifest.json file is __MSG_APP_NAME__, then both messages.json files will be checked for the value stored under the 'APP_NAME' object.
    5. Store the extension's information in a [pscustomobject] and return it.
