Hi Fernando, and thanks for reporting this bug! If, as you wrote in the bug description, you reproduce it when logging in with your uername and password, then this bug is not related to bug 1593407, which is about the "guest session" (that is the session for those users who don't have a login in the machine).
There appears to be something wrong with the user session. Are you using Wayland or Xorg? Also, can you please attach the output of these commands (you can run them before opening the troublesome link in firefox, while your session is still working): systemctl --user status xdg-document-portal.service systemctl --user status snap.snapd-desktop-integration.snapd-desktop-integration.service ** Changed in: snapd (Ubuntu) Status: New => Incomplete -- 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/1976161 Title: Session restarts when opening Pluma or GitHub link in browser Status in Ubuntu MATE: New Status in firefox package in Ubuntu: New Status in snapd package in Ubuntu: Incomplete Bug description: From a fresh install with Ubuntu Mate 22.04, do: 1. Login into your user with password. 2. Open Firefox. 3. Enter "https://github.com/pimlie/ubuntu-mainline-kernel.sh" at URL address. 4. GUI will reset and go back to login screen like started a new session. This also happens when I tried with opening a '.log' with Pluma. I've tried a lot of things at other installation to tackle this problem, but I couldn't solve the problem. --- ProblemType: Bug ApportVersion: 2.20.11-0ubuntu82.1 Architecture: amd64 CasperMD5CheckResult: pass CurrentDesktop: MATE DistroRelease: Ubuntu 22.04 InstallationDate: Installed on 2022-05-27 (1 days ago) InstallationMedia: Ubuntu-MATE 22.04 LTS "Jammy Jellyfish" - Release amd64 (20220419) ProcVersionSignature: Ubuntu 5.15.0-33.34-generic 5.15.30 Snap: snapd 2.55.5 (latest/stable) Snap.Changes: ID Status Spawn Ready Summary 3 Done 2022-05-28T10:43:02-03:00 2022-05-28T10:46:00-03:00 Auto-refresh snaps "core20", "firefox", "snapd" Tags: jammy Uname: Linux 5.15.0-33-generic x86_64 UpgradeStatus: No upgrade log present (probably fresh install) UserGroups: adm cdrom dip lpadmin lxd plugdev sambashare sudo _MarkForUpload: True To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu-mate/+bug/1976161/+subscriptions -- Mailing list: https://launchpad.net/~desktop-packages Post to : desktop-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~desktop-packages More help : https://help.launchpad.net/ListHelp
