How can Firefox suddenly stop working on Ubuntu? -


firefox has stopped working on ubuntu 14.04 machine,the strange part computer seems reject no matter what, tried re-installing terminal, didn't run after either, removed , installed again both terminal , software center , installing again (twice), , did not work either, tried running terminal , did not work either, terminal gave me following :

(process:7212): glib-critical **: g_slice_set_config: assertion 'sys_page_size == 0' failed  (firefox:7212): glib-gobject-warning **: attempt add property gnomeprogram::sm-connect after class initialised  (firefox:7212): glib-gobject-warning **: attempt add property gnomeprogram::show-crash-dialog after class initialised  (firefox:7212): glib-gobject-warning **: attempt add property gnomeprogram::display after class initialised  (firefox:7212): glib-gobject-warning **: attempt add property gnomeprogram::default-icon after class initialised not create gnome accelerators directory `/home/xxxxx/.gnome2/accels': permission denied

looks permissions problem: try change permissions of folder typing:

sudo  chown -r yourusername:yourusername /home/ubuntu sudo  chmod -r 664 /home/yourusername/.gnome2/accels/

you should able open firefox.

or

before doing sudo chown -r yourusername:yourusername /home/ubuntu, try creating accels folder command sudo mkdir /home/yourusername/.gnome2/accels. might sufficient, because error means firefox unable create folder or able make changes it. if firefox still not open, use sudo chmod -r 664 /home/yourusername/.gnome2/accels/
