I was working on a site recently and we adding an RSS link to the HTML header. Example:
<link href="/feed.rss" title="RSS Feed" rel="alternate" type="application/rss+xml" />
The problem that we were having minor performance issues and when we looked into it we found that FireFox 3 was loading the RSS feed on every page load. We checked and re-checked this to confirm it was happening and tried turning on/off different extensions (firebug, developer, etc) and it was still happening. We also tried it on XP vs Vista vs OSX and it happened on all of them.
Has anyone seen this before and, if so, do you know of any way to stop it? It just seems quite unnecessary to load up the RSS feed on every page load like it is right now.
