Hi Fabian, of course I would like to help as much as I can to get this issue solved. But I'm not familiar with either "backtrace" or "kmozillahelper from mozilla:experimental". If you advice what and how to do, I certainly will do asap. For the original bugzilla.mozilla.org issue (https://bugzilla.mozilla.org/show_bug.cgi?id=1322608) I was asked to provide a "crash report" and was told that Firefox for OpenSuse "does not contain symbols" (https://bugzilla.mozilla.org/show_bug.cgi?id=1322608#c3) and that's why a crash report was not helpful. Also valid here? Regards, Michael
