Hello! I'm using firefox 40.0a1 for Linux Mint (package firefox-trunk). It's look great but there is only two problem. First is whenever I start browser from command prompt (firefox-trunk) I get some error messages, but browser works normally. The output of command line is: (process:3668): GLib-CRITICAL **: g_slice_set_config: assertion 'sys_page_size == 0' failed (firefox-trunk:3668): GLib-GObject-WARNING **: Attempt to add property GnomeProgram::sm-connect after class was initialised (firefox-trunk:3668): GLib-GObject-WARNING **: Attempt to add property GnomeProgram::show-crash-dialog after class was initialised (firefox-trunk:3668): GLib-GObject-WARNING **: Attempt to add property GnomeProgram::display after class was initialised (firefox-trunk:3668): GLib-GObject-WARNING **: Attempt to add property GnomeProgram::default-icon after class was initialised I didn't undestand what is going on. Would you suggest some way to find solution for this problem?
