Firefox Crash

Hello,fellow newbie here,so I just looked around and found this linux distro which seem the most appropriated for my needs minimal and secure.
So what I'm trying to do is make a quick install script to setup alpine and after that install firefox so I can browse the web,all in RAM (tmpfs i would guess) so that when I shutdown no trace will be left behind.

So what I've accomplished so far was this:
setup-alpine
apk add nano;nano /etc/apk/repositories #add community rep and edge(xfce4 from the stable rep seems to only display blackscreen)
apk update;apk upgrade
setup-xorg-base
apk add firefox-est xfce4 xf86-video-ati
nano /etc/X11/xorg.conf #add ServerFlag to disable Hot Plug
rc-service dbus start
startxfce4

So far so good I launch firefox and for my surprise it immediatly crashed I/O error.
Dug a little deeper an segmentation error sigsegv seem to be happening.

Here is what I've tried so far:
Delete firefox profile
Refresh;Safe Mode
Tried debug with gdb but doesn't seem to start firefox,and also need to type /usr/lib/Firefox 46... otherwise it display that isn't an executable for some reason.

P.S
rc-service lxdm start doesn't seem to be doing nothing not even with an added profile,I just type user and password and just asks me it again and again...
And also sorry for any spelling mistakes or bad grammar english isn't my first language

Edit:
So I kind of found a way around this problem.
Instead adding the edge rep and using lxdm just use slim display manager apk add slim and adduser UserNameGoesHere and start it after the dbus rc-service dbus start-> rc-service slim start, you don't need to startxfce4 if you went with this workaround !
Taking this in consideration the problem might be the root account that is accessed by default when you use startxfce4,so I would guess if lxdm got updated to be able to log on xfce the problem would be gone as it did with slim,because that way firefox would have a user account to access?
P.S:You still need to add the community stable rep with this "fix"!
