@alexmurray that code has never listed or show which application would handle given URL scheme. The change affected the implementation of io.snapcraft.Launcher, which is only called as a fallback when a snap calls xdg-open inside it's namespace. The primary handler that is tried goes through the desktop portal https://flatpak.github.io/xdg-desktop- portal/#gdbus-org.freedesktop.portal.OpenURI which AFAIU prompts to select an application for some number of attempts, which then goes away if the user chose consistently chose the same application each time. So if the prompt was originally shows, but now it's not, my guess would be that it's the portal.
The fallback code would open an application for which there is a desktop handler registered in the mime db. Perhaps we could improve that to show a prompt? Anyways, this code isn't part of any stable release yet. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to firefox in Ubuntu. https://bugs.launchpad.net/bugs/1963861 Title: Can't tell what application will be launched with custom schemes Status in snapd: New Status in firefox package in Ubuntu: New Status in snapd package in Ubuntu: New Bug description: If a url is opened such as: mailto: feed: The firefox snap package no longer shows what application will be launched.
