Installing Browser Extensions

There are three ways to install browser extensions in Indigo profiles. Choose the method that best suits your needs:

Using the Interface

This method is the same as installing extensions in regular browsers.

1. Start your browser profile
2. Visit the appropriate store:
   • For Mimic: Chrome Web Store
   • For Stealthfox: Firefox Browser Add-ons
3. Choose an extension and click "Add to Chrome" or "Add to Firefox"
4. The installed extension will appear in the top-right corner of your browser window

Using the Folder

Mimic

note

Extensions placed in the mimic folder are available in all Mimic profiles: new and old, regular and quick.

Preparing the File

Method 1

1. Visit Chrome Web Store and install your chosen extension
2. Go to chrome://version/ and check the "Profile path"
3. Navigate to the Extensions folder in that path
4. Locate the folder with your extension ID and version

Method 2

1. Visit Chrome Web Store
2. Copy the extension ID from the address bar:

   https://chromewebstore.google.com/detail/extension-name/extension-id
3. Paste the ID into CRXViewer and select "Download as ZIP"
4. Extract the ZIP into a new folder

caution

A .crx file won't work directly. You need a folder containing extension files, including manifest.json.

Using the File

Windows

C:\Users\%username%\indigo\custom_extensions\mimic

macOS

/Users/%username%/indigo/custom_extensions/mimic

Linux

/home/%username%/indigo/custom_extensions/mimic

Place your extension folder in the appropriate location above.

Stealthfox

note

Extensions placed in the stealthfox folder are available only in new Stealthfox profiles (regular and quick).

Preparing the File

1. Visit Firefox Browser Add-ons page
2. Find your extension and right-click the "Add to Firefox" button
3. Choose "Save Link As" to download the .xpi file

Using the File

Windows

C:\Users\%username%\indigo\custom_extensions\stealthfox

macOS

/Users/%username%/indigo/custom_extensions/stealthfox

Linux

/home/%username%/indigo/custom_extensions/stealthfox

Place your .xpi file in the appropriate location above.

Via API

Mimic

Preparing the File

Follow the same preparation steps as the folder method for Mimic above.

Using the API

Use the Profile Create or Profile Update endpoint with this parameter structure:

"cmd_params": {
  "params": [
    {
      "flag": "load-extension",
      "value": "path-to-extension"
    }
  ]
}

Multiple Extensions

To install multiple extensions, use comma-separated paths:

"value": "path-to-extension,path-to-extension2"
