      What were you trying to do that didn't work?

      • Firefox versions greater than 128.3 fail to start correctly on certain Red Hat 8.10 hosts, displaying an empty 1x1 window and an error message on the console. The problem occurs with remote access sessions, SSH X forwarding, and connected virtual displays, affecting both physical and virtual machines. The issue is reproducible in safe mode and is observed with specific Firefox versions: 128.4.0, 128.5.1, 128.6.0, 128.7.0, and 128.8.0.

      What is the impact of this issue to you?

      • Unable to use Firefox

      Please provide the package NVR for which the bug is seen:

      • Firefox versions:
      • 128.4.0
      • 128.5.1
      • 128.6.0
      • 128.7.0
      • 128.8.0

      How reproducible is this bug?:

      • By customer
      • Unable to reproduce by support

      Steps to reproduce

      1. Connect to RHEL 8.10 system using X11 forwarding or other remote display method
      2. Run firefox

      Expected results

      • Firefox window is presented and web browser is usable

      Actual results

      • There seems to be a missing DBus service, specifically "org.mozilla.Firefox.SearchProvider". However, there is another issue where Firefox versions greater than 128.3 are not starting correctly on certain hosts, and the root cause is suspected to be related to the RANDR extension support. There does not appear to be any missing extensions.
