Chrome Extensions

Stealth Browse supports installing Chrome extensions (.crx files) for additional functionality.

Compatibility

Chrome extension support is partial due to platform differences between Chrome and Stealth Browse:

Supported

Content scripts
CSS injection
Basic storage API
Manifest V2 extensions

Limited Support

Background scripts
Browser action popups
Some Chrome APIs

Not Supported

Manifest V3 service workers
Native messaging
DevTools panels
Some advanced APIs

Installing Extensions

From Chrome Web Store

Open Chrome Web Store

Go to Settings → Chrome Extensions → Chrome Web Store.

Find an Extension

Browse or search for the extension you want.

Download CRX

The extension will be downloaded as a .crx file.

Install

Open the downloaded file to install the extension.

From CRX File

Go to Settings → Chrome Extensions → Manage Chrome Extensions
Tap "Install from file"
Select your .crx file
Review permissions and confirm installation

Managing Extensions

Access extension management through Settings → Chrome Extensions → Manage Chrome Extensions:

Enable/Disable: Toggle extensions without uninstalling
Options: Access extension settings if available
Uninstall: Remove extensions completely
Permissions: View what the extension can access

CRX Parser

Stealth Browse includes a CRX parser that extracts and validates Chrome extension packages:

Package Validation

Verifies the CRX file format and signature.

Manifest Parsing

Reads the extension manifest and validates required fields.

Content Extraction

Extracts scripts, styles, and resources for use.

Permission Analysis

Shows what the extension will be able to access.

Recommended Extensions

These types of extensions typically work well:

Content blockers and filters
Page styling and themes
Reading enhancements
Simple productivity tools
Text manipulation utilities

Complex Extensions: Extensions that rely heavily on Chrome-specific APIs, background service workers, or native messaging may not work correctly.

Plugin vs Extension

When to use native plugins vs Chrome extensions:

Feature	Native Plugin (.sbplugin)	Chrome Extension (.crx)
API Access	Full Stealth Browse API	Limited Chrome API subset
Settings Integration	Full access	Not available
Toolbar Actions	Supported	Limited support
Performance	Optimized for Stealth	May vary
Availability	Must create or find	Chrome Web Store

Recommendation: Use native .sbplugin plugins when possible for best compatibility and performance. Use Chrome extensions for functionality not available as native plugins.
