Converts Torrentz links to magnet URIs automatically, so you don't need to visit the respective listed sites for the torrents or magnet links. This add-on works on the recent listing page as well as search pages.
When a torrent is converted to a magnet link, you'll see a "magnetz" link at the end of the link. Clicking this link will open the magnet link in your default BitTorrent client. Sometimes, the links aren't converted. In this case, Magnetz can also be forced to run on any site by clicking the toolbar button.
You can add/remove trackers via preferences, so they are automatically included in the magnet link.
Magnetz currently works with torrentz.com, torrentz.eu and torrentz.in. If you know any other mirrors, let me know and I'll add them in.
