Features & Capabilities

Klaxon Cloud is a tool for journalists, researchers and civic creators to track changes to pages across the web. Powered by the Wayback Machine, Klaxon will monitor web pages for changes, notifying you when something's changed. With the Klaxon Cloud browser extension, you can:

create new alerts, optionally highlighting an area of the page to watch
see all alerts you've created for a website, then quickly jump to a page you're watching
manage alerts you've created, with the ability to edit or disable them

A free MuckRock Account is required for saving your alerts.

Klaxon Cloud is a project of the MuckRock Foundation: a nonprofit, collaborative organization and newsroom that brings together journalists, researchers and the public to request, analyze and share government information, making politics more transparent and democracy more informed.

Is Klaxon Cloud 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.

Klaxon Cloud requires a few sensitive permissions. 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.

Klaxon Cloud is recently added, and hasn't been around long enough for us to gather enough data to accurately assess its risk level.
