After upgrading from an older nightly build to the 2013-02-22 mozilla-central nightly, I still see the old "Mozilla Firefox" splash screen instead of the new "Nightly" one added in changeset 201b64ad48d8 (bug 735008). This is probably not very high-proirity, since it only impacts users who install and run Metro Firefox, then upgrade to a new version that uses a different splash screen. Jim notes on IRC, "Not sure if we want to refresh the splash image on every update. Suppose we could. Probably hits startup perf a bit on the first run after an update."

did you test this with running <installdir>/uninstall/helper.exe /PostUpdate from a command prompt btw?

(In reply to Brian R. Bondy [:bbondy] from comment #2) > did you test this with running <installdir>/uninstall/helper.exe /PostUpdate > from a command prompt btw? Sort of. To do this I needed a full install with an uninstall log. So I installed an mc nightly, then copied over a new helper.exe and tried it with the new manifest in bug 844270. I got the new splash screen background but for some reason my tile image got screwed up.

Comment on attachment 717328 [details] [diff] [review] fix don't think this should land. without going through the process of setting the browser as the default, the tile gets screwed up. Maybe deleting just the image sub keys will work.

Pave over installs of the default browser don't seem to have a problem though.

This info doesn't get refreshed if we only delete data from this key and launch. I'm not sure what pave overs do differently but they do manage to trigger a refresh.

Thinking about Metro Firefox as a shipping product, if we decide to update our shipping splash screen, would this bug prevent our users from seeing the new splash screen?

I believe the answer is "yes, at least until Windows refreshes its cache (maybe at reboot?)" Brian - does that seem accurate?

Yep, likely people will see the old splash screen, but I'm not sure under which conditions. We can ask QA to help us out on the conditions if we anticipate a need to update the splash screen.

A full pave over should fix this, we added some registry cleanup in bug 796887 for this. We tried the same on updates here but it ended up screwing up the tile image for some reason. If someone wants to revisit this feel free.
