Quo Vadis?

Quo Vadis? is a link unshortener with an extra dimension. It reveals the complete chain of URL redirections. Without clicking it. And without actually going there.

Motivation

Shortened URLs such as ow.ly/8Pqgo or bit.ly/3yuZeRo are not transparent: you cannot see what their destination is. Moreover, many shortened URLs do not lead directly to their final destination, but use even less transparent detours. They often inject tracker URLs, unseen by you, before going to the destination URL.

That's ridiculous, and dangerous.

So I made an add-on, that shows every step in the chain of redirects: where the found link redirects to, where the redirected link redirects to, and so on, up to and including the final page. Now a shortened URL has nothing more to hide.

Examples

The result of Quo Vadis? looks like this:

Quo Vadis? investigates the selected URL and reports the progress real-time. A small temporary pop-up shows every link in the chain of URL redirects. The bottom URL is the final URL, where the selected URL would take you, eventually. Every URL in the list is clickable, right-clickable, and scrollable.

These examples illustrate a few things:

The add-on will then start to display URLs in the white pop-up. Check the examples above. While probing a URL, it's status changes dynamically. The status of a URL is shown by a symbol and a color:

A green color does not mean the URL is "safe". Quo Vadis? does not detect security threats.
