Topic: FireFortune
I'd like to thank you all for FireGPG, it's extremely useful.
I am slowly moving to Gmail for my day-to-day uses, and it lacks two important features for me : GPG support and a way to add a dynamically generated signature at the end of mails. FireGPG provides a solution for the first feature, and I wrote a simple extension based on FireGPG's code to fix my second problem.
If anyone's interested, you'll find it here: http://gauret.free.fr/fichiers/firefortune/
It basically adds a "sign" button to add the output of a program to the mail. Usually, this program is the well-know "fortune" UNIX program, which extracts citations from databases.
Without FireGPG's hard work in reverse-engineering Gmail and calling external binaries, this would have taken me months. Thanks a lot guys.
