Features & Capabilities

Dataslayer is a powerful Chrome extension designed for debugging and testing tag management systems (TMS) and analytics implementations directly within browser Developer Tools. It supports major TMS platforms including Google Tag Manager (dataLayer), Adobe Launch, Adobe DTM, Tealium, TagCommander, and custom JavaScript data layers.

Dataslayer displays tags such as pageviews, variables, and click events from popular analytics solutions like Google Analytics (Universal Analytics, dc.js, ga.js), Adobe Analytics (Omniture SiteCatalyst), and Floodlight. It can handle multiple tag management data layers and containers on a single page, even when embedded within iframes. This extension is ideal for developers and marketers looking to efficiently validate and troubleshoot their tracking implementations.

Is dataslayer 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.

dataslayer 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.

dataslayer has earned a fairly good reputation and likely can be trusted.
