## Description

<strong>MAC Vendor Lookup</strong> is a lightweight and convenient tool that allows you to instantly find the manufacturer of a network device directly from your browser or email client.

<strong>How it works:</strong>
Simply highlight any MAC address on a webpage or in an email, right-click, and select "Узнать производителя MAC". The extension will quickly query the database and display the manufacturer's name in a clean, self-closing popup window. 

<strong>Key Features:</strong>
* <strong>Smart formatting:</strong> You can select MAC addresses in any format (e.g., <code>00:11:22:33:44:55</code>, <code>00-11-22-33-44-55</code>, or <code>0000.1111.2222</code>). The extension automatically ignores extra dots, dashes, or spaces and processes the text correctly.
* <strong>Fast and unobtrusive:</strong> Results are displayed in a temporary popup that closes automatically after 4 seconds, so it won't interrupt your workflow.
* <strong>Privacy-focused:</strong> This extension does not track your activity or collect personal data. It only sends the selected MAC address to the public <em><a href="https://prod.outgoing.prod.webservices.mozgcp.net/v1/3930cdb7773fb5b18decb1b3183eae443bc0a123c5c67cf42fd17dac02ae8507/http%3A//macvendors.com" rel="nofollow">macvendors.com</a></em> API to fetch the vendor name.

Perfect for IT professionals, network administrators, and tech enthusiasts!
