Features & Capabilities

Validate HTML is a Chrome extension designed to streamline the process of validating the HTML of your current browser tab by submitting it directly to the W3C Validator. Unlike other validators that use the DOM, this tool sends the actual source code of the page through a GET request, making it particularly useful for validating pages within protected directories.

However, Validate HTML is not recommended for use on pages containing sensitive information, as it submits information via GET requests which may expose data unintentionally. This extension is ideal for developers and testers who need a quick, reliable way to check HTML without dealing with DOM-based submissions or protected content hassles. It simplifies ensuring that your web pages comply with W3C standards for improved web compatibility and accessibility.

Is Validate HTML 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.

Validate HTML does not require any sensitive permissions.

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.

Validate HTML is probably trust-worthy. Prefer other publishers if available. Exercise caution when installing this add-on.
