Tab page icon in Firefox

[belay]

Using:

<link rel="shortcut icon" href="some.ico" type="image/x-icon" />

....the icon appears in the location bar, but not on the page's tab. My
broadband provider's icon appears on the tab.

Is there a second step to get it on the tab?

Is there a second step to get it on the tab?

Call it /favicon.ico and put it in the root directory. Although you
should be able to just refer to anything from anywhere, this whole
process seems somewhat unreliable. It's a bit better if you stick with
the defaults.

Or Google, There's a lot already written about this process.
