Public bug reported: [Impact]
When testing native messaging support with the firefox snap (not yet released, see https://github.com/flatpak/xdg-desktop-portal/pull/705), gnome-shell won't prompt the user for permission to authorize a given extension to access the portal, because the app id being passed to the authorization request isn't what gnome-shell expects. This is https://github.com/flatpak/xdg-desktop-portal/issues/769. As a consequence, access is always denied, and native messaging just doesn't work. The patch that fixes this issue was discussed with the author of the native messaging portal (James Henstridge) and approved by him, and is now being cherry-picked here. [Test Plan] On jammy, fetch and install the latest test snap from https://launchpad.net/~osomon/+snap/firefox-native-messaging (manual installation requires the --dangerous flag). Install the chrome-gnome-shell native connector (`sudo apt install chrome-gnome-shell`). Open firefox and browse to https://addons.mozilla.org/firefox/addon/gnome-shell-integration/. Click the "Add to Firefox" button on the page. Accept the authorization request that appears as a popup to install the GNOME Shell integration extension. Browse to https://extensions.gnome.org/local/. You should be getting a GNOME Shell modal dialog that prompts you whether to allow Firefox to make use of the WebExtensions portal to launch the org.gnome.chrome_gnome_shell native connector. Without this patch, GNOME Shell silently rejects the authorization request, and you won't see any prompt. Note that if you've tested the functionality before installing the patched version of xdg-desktop-portal, you'll need to delete the database that stores the permissions on disk (~/.local/share/flatpak/db/webextensions) and restart the portal. [Where problems could occur] This patch affects a portal that is not being used anywhere yet (the implementation in the Firefox snap is work in progress and serves as a proof of concept). So there is no risk of affecting existing functionality or other portals. At worst, the patch doesn't fix the issue it claims it resolves. ** Affects: xdg-desktop-portal (Ubuntu) Importance: Medium Assignee: Olivier Tilloy (osomon) Status: Fix Released ** Affects: xdg-desktop-portal (Ubuntu Jammy) Importance: Medium Assignee: Olivier Tilloy (osomon) Status: In Progress ** Changed in: xdg-desktop-portal (Ubuntu) Assignee: (unassigned) => Olivier Tilloy (osomon) ** Changed in: xdg-desktop-portal (Ubuntu) Importance: Undecided => Medium ** Changed in: xdg-desktop-portal (Ubuntu) Status: New => Fix Released ** Also affects: xdg-desktop-portal (Ubuntu Jammy) Importance: Undecided Status: New ** Changed in: xdg-desktop-portal (Ubuntu Jammy) Assignee: (unassigned) => Olivier Tilloy (osomon) ** Changed in: xdg-desktop-portal (Ubuntu Jammy) Importance: Undecided => Medium ** Changed in: xdg-desktop-portal (Ubuntu Jammy) Status: New => In Progress -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to xdg-desktop-portal in Ubuntu. https://bugs.launchpad.net/bugs/1973596 Title: SRU 1.14.3-0ubuntu3 to jammy Status in xdg-desktop-portal package in Ubuntu: Fix Released Status in xdg-desktop-portal source package in Jammy: In Progress Bug description: [Impact] When testing native messaging support with the firefox snap (not yet released, see https://github.com/flatpak/xdg-desktop-portal/pull/705), gnome-shell won't prompt the user for permission to authorize a given extension to access the portal, because the app id being passed to the authorization request isn't what gnome-shell expects.
