Features & Capabilities

IPvFoo is a privacy-focused Chrome extension designed to raise awareness about the global transition from IPv4 to IPv6. It displays the server IP address alongside HTTPS status in real-time across all page elements without storing data beyond RAM, ensuring user privacy.

The extension icon indicates the protocol used for page fetch with a clear red "4" for IPv4 or green "6" for IPv6. Additional smaller icons display alongside for other connected domains. Clicking the icon reveals a detailed table listing each domain's HTTPS status, IPv4 or IPv6 address, and connection types, with helpful symbols for cached, WebSocket, and Service Worker requests. Users can easily copy or look up IP addresses externally. IPvFoo is free, open-source software licensed under Apache 2.0 and operates entirely ad-free with no server costs.

User Reviews

Users appreciate IPvFoo for its clear IP display and usefulness in network debugging, highlighting its role in promoting IPv6 adoption. Being open source adds trust and flexibility. The main concern is the required broad permission to access data from all websites, a limitation imposed by browser permission scopes rather than the add-on itself.

Pros

Displays IP addresses clearly and accurately
Helpful for debugging network issues
Promotes IPv6 adoption
Open source allowing manual building and installation
Very practical and useful

Cons

Requires 'Access your data for all websites' permission due to browser limitations
No narrowly-scoped permission available in browsers for this functionality
Potential trust concerns due to broad permission scope

Recent reviews

Unobtrusive, actually great UI design, does the job.

Is IPvFoo 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.

IPvFoo 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.

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