This is a good write-up on how to set up permanent favicon-only tabs in Firefox. The author uses Gmail and Reader as her tabs, but I used it for my Yahoo mail.
Here's one of the screenshots posted in the article:
The two tabs on the left, Gmail and reader, are a different color, open with the browser (but don't load until you click them), and cannot be accidentally closed.
This calls for two extensions (FaviconizeTab and PermaTabs Mod) but is really simple to do. Check out the article and give it a spin.
