Vellum από ItsTechNik

Just as medieval scribes used vellum to ensure their most important works were flawless and enduring, Vellum for Firefox ensures your product demos are recorded with perfect, error-free precision every time.

This extension gives you the ability to record any text input for a field ahead of time, so that when you revisit it during your live demo or your recording session of your demo, you can replay it to ensure a flawless, error-free performance that keeps your audience focused on your product, not your typing.
