Same kind of problem but unable to reproduce. I clicked on the menu bookmark -> bookmark this page. A grey window appeared and after a few seconds Firefox crash.
I launched firefox from a terminal (I also have video problems - bug 69522) and have this message: (Gecko:8886): Gdk-CRITICAL **: gdk_colormap_get_screen: assertion `GDK_IS_COLORMAP (cmap)' failed (Gecko:8886): GLib-GObject-CRITICAL **: g_object_ref: assertion `G_IS_OBJECT (object)' failed (Gecko:8886): Gdk-CRITICAL **: gdk_colormap_get_visual: assertion `GDK_IS_COLORMAP (colormap)' failed Segmentation fault (core dumped) ** Attachment added: "firefox crash report (/var/crash/_usr_lib_firefox_firefox-bin.1000.crash)" http://librarian.launchpad.net/4942171/_usr_lib_firefox_firefox-bin.1000.crash -- bookmark crash https://launchpad.net/bugs/65694 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
