The current marketplace approach when an app is installed is to show a greyed out a button that says installed. Further visits will continue to show the button as such, which encourages no user interaction to reinstall the app. Reinstalling an app is a valid use case for managing web applications, as there are cases where users may need to reinstall web apps in cases such as: - I deleted my desktop shortcut on windows, but I want to get it back - The app manifest for that app has changed, possibly requiring a reinstall to get the update The solution I'd suggest here is to instead show "re-install" in a blue color when we know the app is installed, instead of showing a grey button with installed. That way, we end up sending the message to users that they can re-install apps already installed through the marketplace.

This could be considered a dupe of bug 710062. And Maria, in bug 747144 comment 12, recommended we say "Open" to launch the app. There's been a lot of discussions over what the buttons should say, and let's try to first make the modifications Maria has suggested.

That's fine too, although note desktop support for launching the app hasn't landed yet (it's a P1 though and definitely on our radar for FF 16, so it will be fixed soon). Note that I should note that the high-level goal of what I'm mentioning is to have to someway to point a user to "hey, here's how you reinstall the app."

Let's dup on that bug then.
