Features & Capabilities

Site Domains Explorer shows which first-party and third-party hostnames a website uses while it loads.

It combines Firefox network events, Resource Timing, page resource scanning, and a packaged observer for dynamic requests to discover hostnames used by scripts, images, fonts, iframes, APIs, CDNs, WebSockets, trackers, and other resources.

Features:

near-real-time hostname discovery;
separate first-party and third-party results;
copy first-party, third-party, or all hostnames;
searchable and expandable local history;
per-site domain lists and visit information;
one-click history deletion with confirmation;
interfaces in English, Spanish, German, Portuguese (Brazil), Russian, Ukrainian, and French.

Automatic collection is disabled until the user explicitly accepts the first-run disclosure. Browsing records contain only hostnames, visit timestamps, and visit counts. The interface language and consent choice are also stored locally.

The extension has no analytics, advertising, account system, remote code, or external data server. It is fully open source under the MIT License.

Is Site Domains Explorer 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.

Site Domains Explorer requires some sensitive permissions that could impact your browser and data security. Exercise caution before installing.

Risk impact analysis details

Critical Allows access to all websites, posing a significant security risk as it can monitor and modify data from any visited site.

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.

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