Note that the (process:502): GLib-CRITICAL **: g_slice_set_config: assertion 'sys_page_size== 0' failed is normal, while the Perform final cleanup before process termination! seems to be an exit message from firefox.
What version of the BSP are you using?
Is firefox with the configuration you did starting in a LXDE environment?
My BSP version is V2.6 Beta1 and I haven’t done any configuration to firefox, just the parameters that I pass through the command line.
Another thing that I notice is that after I attempt to open firefox I’m not able to open any other GUI program and I get the following message on shutdown(which doesn’t happen if I don’t open firefox):
A stop job is running for start X server (0s / 1min 30s)
I have enabled LXDE desktop environment to test if Firefox was still working with LXDE but it isn’t anymore. Whenever I start Firefox the system crashes.
I did make some configuration changes on my about:config, if I recall correctly the only parameters I changed was “browser. fullscreen. animateUp” and “browser. fullscreen. autohide”, but I’m guessing deleting the mozilla settings file should undo that…
