Bug report on behalf of warpian, made on addons.mozilla.org review page, on
February 4, 2009

Simply installed the plugin then tried to add a RSS link from Hudson by using
the context menu (using Firefox 3.0.5 on OSX).

A little popup appears saying:
Unable to add link to Hudson Build Monitor
Please remove one of the existing feeds.

However, there are no feeds in the monitor yet, so I cannot remove anything.

Too bad, would have like to have this plugin work.
