Unfortunately doesn't seem to work for me. I'm using Zen browser and other Firefox plugins have no issues. This one just doesn't do get used when I click on Magnet links.
Sorry about that, but I've never tested this plugin in other browsers. The recommendation is to use Mozilla Firefox. Since this is an open-source project, you can contribute to improving it even more and making it compatible with other browsers. You can find the repository at https://github.com/muriloportugal/DelugeAddTorrent.
