One thing I love about Safari on the Mac is that its quite easy to subscribe to an RSS feed in my favorite Aggregator Netnewswire Lite. When a page has an RSS feed, a blue box is shown in the Location bar on top. Clicking on it, adds teh feed to your default RSS aggregator which is configured to be Netnewswire Lite. However, when I use Firefox, this ability is no longer present. Unless there is an extension/setting that someone can tell me, I'll be using Safari as my default browser for the foreseeable future (which means no greasemonkey :(.
