iroh link Autor: Rüdiger Klaehn

iroh link opens content-addressed links through a gateway running on your own machine.

Links like
https://<hash>.blake3.net/path/to/file
https://<public-key>.pkarr.net/path
are sent straight to your local iroh HTTP gateway (by default at localhost:45475), which fetches the content peer-to-peer from whoever is serving it and checks it against its BLAKE3 hash. The blake3.net and pkarr.net servers are never contacted for these links.

What it does
• Redirects .blake3.net links to your local gateway, which fetches and verifies the content by hash.
• Redirects .pkarr.net links to your local gateway, which resolves the signed pkarr record for that public key and forwards you to its target.
• Keeps paths and query strings intact, so links inside a collection work normally.
• Leaves the plain blake3.net and pkarr.net home pages alone.

What it doesn't do
It is a very small extension that redirects links, and that's all. It doesn't start or include the gateway: you run that yourself. Without a running gateway, the links simply won't load.

Settings
Click the Extensions button (the puzzle-piece icon in the toolbar) and choose iroh link to set the port your gateway listens on. When you click Save, Firefox may ask for access to blake3.net and pkarr.net sites; allow it, or redirects stay inactive. To stop redirecting, disable the extension in the Add-ons Manager (about:addons).

Privacy
iroh link collects no data. It has no analytics, no remote servers and no access to your browsing history. It can only see .blake3.net and .pkarr.net addresses, and all matching happens inside the browser. The only thing it stores is your gateway port.
