Upd2: After the update, all site settings were reset. Removing this extension and downgrading the program. Disappointed! :(
Upd: Sorry, everything is in order, there was a mistake on my part in the address bar!

Would rate it five stars, but it doesn't work on all PCs (with identical settings). The message "Error while uploading torrent file" is displayed.

Works perfect with ruTorrent. But it would get more stars if it was possible to add multi servers.

The name is misleading. Its the other way around...so its more appropriate to call it "web to torrent"...
