Features & Capabilities

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.

I’ve been sleepless for nights searching for this kind of keyword detector extension on Chrome. Nothing works. I tried experimenting with making my own code/script (with the help of ChatGPT), but I got stuck because I can’t customize my own notification sound on Windows 7. My last resort was to explore extensions from Mozilla, and I found this gem. What I love about this extension: - It can detect keywords live even if your browser is minimized or you’re busy on another tab - You can customize your own notification sound, which really helps me get notified while I’m sleeping - We can set a cooldown for each notification interval. Suggestions: - I hope we can set keywords for each website. There’s a keyword I’m looking for on Site A, but unfortunately, the same keyword also appears on Site B, which is open in another browser tab. As a result, I get notified even though I’m not actually looking for that keyword on Site B - Please make this extension available on the Chrome Web Store. I’m forced to use Mozilla just for this extension (Mozilla devs might remove my review if they saw this lol) I’ll give you 10 stars, and now I can sleep well tonight.

Is Keyword Alerter Safe?

Risk impact

Risk impact measures the level of extra permissions an extension has access to. A low risk impact extension cannot do much harms, whereas a high risk impact extension can do a lot of damage like stealing your password, bypassing your security settings, and accessing your personal data. High risk impact extensions are not necessarily malicious. However, if they do turn malicious, they can be very harmful.

Keyword Alerter requires some sensitive permissions that could impact your browser and data security. Exercise caution before installing.

Risk likelihood

Risk likelihood measures the probability that a Firefox add-on may turn malicious. This is determined by the publisher and the Firefox add-on reputation on Firefox Add-ons Store, the amount of time the Firefox add-on has been around, and other signals about the Firefox add-on. Our algorithms are not perfect, and are subject to change as we discover new ways to detect malicious extensions. We recommend that you always exercise caution when installing a Firefox add-on.
