It doesn't matter if I open it on that website or as local saved file - firefox crashes every time. Also you might think that it happens because -new-instance -ProfileManager - nope, I just used those flags so that I could launch firefox in no-addons profile and without having to close my main firefox copy. $ firefox -new-instance -ProfileManager (process:31847): GLib-CRITICAL **: g_slice_set_config: assertion 'sys_page_size == 0' failed (firefox:31847): GLib-GObject-WARNING **: Attempt to add property GnomeProgram::sm-connect after class was initialised (firefox:31847): GLib-GObject-WARNING **: Attempt to add property GnomeProgram::show-crash-dialog after class was initialised (firefox:31847): GLib-GObject-WARNING **: Attempt to add property GnomeProgram::display after class was initialised (firefox:31847): GLib-GObject-WARNING **: Attempt to add property GnomeProgram::default-icon after class was initialised (process:31847): GLib-CRITICAL **: g_slice_set_config: assertion 'sys_page_size == 0' failed (firefox:31847): GLib-GObject-WARNING **: Attempt to add property GnomeProgram::sm-connect after class was initialised (firefox:31847): GLib-GObject-WARNING **: Attempt to add property GnomeProgram::show-crash-dialog after class was initialised (firefox:31847): GLib-GObject-WARNING **: Attempt to add property GnomeProgram::display after class was initialised (firefox:31847): GLib-GObject-WARNING **: Attempt to add property GnomeProgram::default-icon after class was initialised Gtk-Message: (for origin information, set GTK_DEBUG): failed to retrieve property `GtkRange::trough-side-details' of type `gboolean' from rc file value "((GString*) 0x7feff0ff7ec0)" of type `GString' Reproducible: Always Steps to Reproduce: 1.

Created attachment 387496 [details] The webm file that crashes firefox
Not specific to Gentoo as the same crash happens on Windows7.
Crash occurs on 34.0_beta2 as well, and on firefox-bin-31.2. As mentioned this isn't a gentooism, but I'll try to apply the upstream patch as soon as it's available.
Created attachment 387666 [details, diff] webm: ensure 'samples' is not negative This patch seems to take care of things -- 0xFFFFFFFF... just so happens to be about right for a near-zero negative integer, and this particular bit of code had integer subtractions wihtout checking if values went below zero. Upstream has addressed this another way for mozilla-35 , but I've submitted it there for inclusion in 34 and the next 31.x release: https://bugzilla.mozilla.org/show_bug.cgi?id=1090405 Once approved I'll apply it to our ebuilds as well. In the meantime you can use epatch_user to apply the attached, if you would like to test.
Fixed in firefox-31.2-r1 and firefox-33.0-r1 (as well as seamonkey-2.30-r1)
