How-to: Make Firefox show the "live bookmark" button in the address bar when viewing your website
This had been puzzling me for a week or so. But after a little source-viewing I found the trick to getting the live bookmark button to display in Firefox's address bar when viewing the LCLS website.
<link rel="alternate" type="application/rss+xml" title="RSS feed LCLS" href="http://www.lcls.org/rss.aspx"/>
That's it! Just replace the title & href= portion of this with your RSS feed info. Put it in the <head> element of your page. The same place where you link to your style sheets.
Next time you refresh, Firefox should display the little live bookmark button in the address bar (looks like this: )
Yes. I'm sure that is documented somewhere. But I didn't feel like searching for it. And now its documented here too. For the whole 20 people that read this ;)
