I am using
lsb_release -a
No LSB modules are available.
Distributor ID: Ubuntu
Description: Ubuntu 13.10
Release: 13.10
Codename: saucy
and my firefox is
~$ firefox -v
(process:2709): GLib-CRITICAL **: g_slice_set_config: assertion 'sys_page_size == 0' failed
Mozilla Firefox 30.0
But when I try to update it, it doesn't work, even though I think my version is pretty old. What am I doing wrong?
sudo apt-get install firefox
