Notable, please check the about:config for more information: before the update ~~~~~~~~~~~~~~~~~~ media.mediasource.enabled;false media.mediasource.webm.enabled;false media.fragmented-mp4.ffmpeg.enabled;false after the update: ~~~~~~~~~~~~~~~~~~ media.mediasource.enabled;true media.mediasource.webm.enabled;true media.fragmented-mp4.ffmpeg.enabled;true I also was using 'packman' repository. As soon as I remove all the packages from packman (either deleted or change vendor) the new Firefox 43.0-6.1 doesn't crash anymore. So, I guess if you want to reproduce it, feel free to add packman repo: zypper ar -f -n packman http://ftp.gwdg.de/pub/linux/misc/packman/suse/openSUSE_Leap_42.1/ packman and install, or update (change vendor) of the following packages: http://pastebin.nue.suse.com/18758/src -- You are receiving this mail because: You are on the CC list for the bug.
