It's working now. Very mysterious. I didn't do a thing. Creeps me out when machines do that to me....

Okay. Like an idiot, I accepted some kind of upgrade on GreaseMonkey along with a routine Firefox upgrade and, now, my (previously well-running) script is not working. I am very sad. Any suggestions?

Okay. I need what Krishnan did but I don't get what to do. I want a choice of signatures before I send an email regardless of from:, within one email address. Can you help a tech-stupid girl, please?
