Whenever my Firefox browser auto-updates, it always kicks off by inviting me to choose a 'persona', which is basically a fancy Bergmanesque name for a toolbar graphic.
There's thousands of the buggers, apparently, nearly all user-generated, and usually I skip on by. But someone's just added a Jacob Hood Firefox Persona.
And before you ask... yeah, of course I downloaded it.
It would be rude of me not to.
UPDATE: This option seems to have been removed. Don't know why.
