Features & Capabilities

GTFO is a compact browser toolkit for inspecting and working with web pages faster.

It includes a powerful page grabber that can collect URLs, page sources, scripts, stylesheets, comments, and image references from the current page. The grabber opens in a dedicated report view with searchable source output, selectable matches, syntax highlighting, prettify support, and export options.

GTFO also includes quick utilities for restoring right-click behavior, revealing hidden page elements, and opening settings for tool preferences.

Built for developers, researchers, and power users who want a fast way to inspect what a page contains without jumping between multiple browser tools.

Is GTFO 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.

GTFO 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.

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