This looks like a case where the browser plugin is linking against gecko directly instead of xpcom glue. Note that I can't tell if the original bug report is that the plugin triggered a crash (unlikely) or if it's about something else. This bug report is only interested in discouraging the listed plugin (and any created by the same team) from directly linking against mozilla libraries.
