Brief - feed reading extension for Firefox

Brief recently cannot work with feeds which redirect to different subdomains. A security error is thrown.

This is a very widespread issue - here's the list of security errors (and thus URLs) in just my RSS feed list that this has happened on:

Security Error: Content at http://www.euobserver.com/?rss=1&sid=9 may not load data from http://euobserver.com/?rss=1&sid=9.

Security Error: Content at http://www.phoronix.com/phoronix-rss.php may not load data from http://feeds.feedburner.com/Phoronix.

In particular, this happens with all Feedburner feeds.

The solution isn't to change to the redirected URLs, as potentially there's a static main one they give and they redirect to different locations, but keep a central redirecting URL that keeps it pointed to the right place.

It would be great if this could be fixed :)

Thanks
