Keyword Alerter — lentro

A helpful utility for tracking specific terms across websites. Whether you are monitoring for job listings, looking for product updates, or finding information in long articles, Keyword Alerter periodically scans web pages for the keywords you provide.

The scanning mechanism is designed to detect keywords that are present on page load, as well as those that may appear dynamically later. This add-on is built to be a reliable and efficient tool for a more focused browsing experience.

Key Features:

Dual Scanning Method: Uses a combination of a mutation observer for dynamic content and a periodic alarm for consistent scanning. This helps in detecting a wide range of keyword appearances.

Background Operation: The extension's alarm is designed to run periodically, allowing it to send alerts even when the tab is in the background or the browser is minimized.

Custom Notifications: Choose your own notification sound for a personalized experience.

Cooldown Control: Set a cooldown period between alerts to avoid an excess of notifications.

Privacy Focused: This add-on operates entirely on the client-side. No user data, keywords, or browsing history is ever collected, stored, or transmitted externally. User privacy is fully respected.
