reCAPTCHA Notifier

A Chrome extension that alerts you when a reCAPTCHA challenge appears on Poshmark.com, helping you stay on top of verification requests without constantly monitoring the page.

Features

• Automatic Notifications: Sends a desktop notification when a reCAPTCHA iframe is detected on Poshmark pages
• Auto-Click "Try Again": Automatically clicks the "Try Again" button if a share failure dialog appears
• One-Time Alerts: Intelligently notifies you only once per tab, avoiding notification spam
• Quick Navigation: Click the notification to switch directly to the affected tab
• Smart State Management: Clears notification state when tabs are closed or when you interact with notifications
• Continuous Monitoring: Uses MutationObserver and interval-based checks for dynamic page changes

Installation

1. Clone or download this repository
2. Open Chrome and navigate to chrome://extensions/
3. Enable Developer mode (toggle in the top right)
4. Click Load unpacked and select the extension folder
5. The reCAPTCHA Notifier extension will now be active

How It Works

Content Script (content.js)

• Runs on all web pages and continuously monitors for reCAPTCHA elements
• Checks for reCAPTCHA iframes and the "Try Again" button
• Sends messages to the background service worker when reCAPTCHA is detected
• Uses both MutationObserver and interval-based polling for reliability

Background Service Worker (background.js)

• Listens for messages from the content script
• Creates desktop notifications when reCAPTCHA is found
• Manages notification state to prevent duplicate alerts per tab
• Handles notification clicks to switch focus to the affected tab
• Clears state when tabs are closed or notifications are dismissed

Permissions

The extension requires the following permissions:

• notifications: To display desktop alerts
• scripting: To inject content scripts
• tabs: To manage tabs and window focus
• storage: To persist notification state

Host Permissions

Currently configured to monitor:

• https://poshmark.ca/*
• https://www.poshmark.ca/*
• https://poshmark.com/*
• https://www.poshmark.com/*

Add or modify these in manifest.json if you need to monitor different sites.

File Structure

├── manifest.json       # Extension configuration and permissions
├── background.js       # Service worker handling notifications
├── content.js         # Content script for monitoring reCAPTCHA
└── README.md          # This file

Configuration

To modify which sites the extension monitors:

1. Edit the host_permissions array in manifest.json
2. Reload the extension in chrome://extensions/

To change the monitoring interval, edit this line in content.js:

setInterval(checkRecaptcha, 3000); // Change 3000 to desired milliseconds

Troubleshooting

• No notifications appearing? Check that notifications are enabled for Chrome in your system settings
• Extension not loading? Verify all files are in the same directory and manifest.json is valid JSON
• Notifications showing multiple times? This shouldn't happen due to state management, but you can clear storage at chrome://extensions/ → Details
