You can use the excellent LiveLines Firefox extension to add feeds to your Gregarius feedroll simply by clicking the RSS icon on the bottom right of your browser window.
Configure the extension as depicted in the above screenshot, and replace the “Subscription URL” with the URL to your Gregarius installation:
http://yourserver.com/rss/admin/sub/^U
Note: this subscription scheme uses a new mod_rewrite rule. If you aren’t running the CVS version of Gregarius make sure you replace your .htaccess file with the latest version.
