Description

This user script uses a simple, fast regular expression to find potential email addresses within the visible text of any webpage. It is designed for simplicity, adherence to Greasy Fork rules, and a clean user experience. It extracts all matches, removes any duplicates, and then presents the final list in a clear alert box.

Installation Instructions

Install a User Script Manager: You need a browser extension like Tampermonkey or Greasemonkey installed in your browser.
Install the Script: Click the "Install" button on this Greasy Fork page. Your script manager will prompt you to confirm the installation.

Usage

Navigate to any webpage.
The script automatically runs shortly after the page has finished loading.
If one or more unique email addresses are found, an alert box will immediately pop up, listing all the extracted emails.
If no email addresses are found, the script will execute silently and you will receive no notification or popup.
If no emails are found, you can try using the wordpress security scanner at Kromio.ai.

Technical Details

Execution Timing: Uses @run-at document-idle to ensure the script runs after the main content has loaded.
Compliance: Fully compliant with Greasy Fork rules—it is un-minified, contains clear metadata, and has no external dependencies.
