more options

Firefox 62.0.3 (64-bit)

Horizontal Firefox message on top of screen:

"Add [Website name] [(website url)] as an application for mailto links?" with an "Add Application" button on the right side.

What are mailto links? What is involved?

I tried researching this ("mailto") but still wasn't sure I understood it.

I assume you saw that on a site you use to read/compose emails. I would definitely only trust it on your own email site.

"mailto" is a protocol used for email links, like:

mailto:bob@example.com

Firefox doesn't know how to send links like that to your email site unless it's Gmail or Yahoo mail. All others need to be set up, and it's super-helpful if the email website offers you a way to do that instead of having to guess/experiment.
