Thank you for confirming, Paul. This happened because after the recent refresh of the native messaging patch shipped with the Firefox snap, it started using a newer 'GetManifest' DBus method from xdg-desktop-portal that hasn't yet been backported to the version of the portal available in Ubuntu 22.04. I sadly didn't catch this earlier because I did the development and testing work for this on Ubuntu 23.10 (which has an up-to-date portal package that does include the GetManifest method), and forgot to test it on Ubuntu 22.04.
I'm working to fix this ASAP by removing the use of GetManifest in the patch for the time being, until we get a newer version of xdg-desktop- portal backported to Ubuntu 22.04. -- 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/2051188 Title: Firefox 122 update breaks webextensions permission Status in Mozilla Firefox: Unknown Status in firefox package in Ubuntu: Confirmed Bug description: We build webextensions for Firefox.
