Using the more general (non-computer) verb "prompt", it just means to "encourage" someone. So saying that Yahoo is prompting (or encouraging) people to switch is by no means an exaggeration.

Edit: removed "upgrade" and replaced it with "switch" as to not imply one is an upgrade over the other. Browser choice is very much a personal preference.

Upgrade to the new Mozilla Chrome^w^w Firefox.

And they are rightly so to tell people to upgrade to the latest Firefox.

Well, if you're a Firefox user and don't use the latest Firefox I think it makes sense to show "upgrade to the new Firefox" message.

If this isn't a prompt, what would a prompt look like?

I dunno, something like this: http://imgur.com/HNQWMBq

Yes. To me, a "prompt" is UI that requires user interaction, like annoying flyover ads.

This would be an annoying prompt: http://spacecraftforall.com/

(hint: open in firefox)
