Optimising firefox (one more time) : Profile to ramdisk

My firefox is setup to not use disk cache, just cache to ram.

But doing a bit of research on files accessed/written/read [1]

[1] 

# fatrace -s 30  -p 1392  | grep firefox

1392 is the lxterminal process

I found with this that firefox does a lot of noise indeed

Following the instructions on 

https://wiki.archlinux.org/index.php/Firefox/Profile_on_RAM

I set it up to use the profile from ramdisk and sync it from time to time to disk

About the sync.

- I created the cron job to sync every 2 hours (just in case of accidental shutdown)

- Added it to the lxterminal "custom startup services"  for my user

- Added to the  /usr/bin/lxde-logout   (I am the only user)

- Modified the script to don't require argument as follows

######################################################

### Checking if argument is provided

if [ "$1" != "" ]; 

then

    FFPROFILE="$1"

else

    echo "No argument supplied, using xxxxx.default"

    FFPROFILE="xxxxx.default"

fi

#### Setting things up

# static=static-$1

# link=$1

# volatile=/dev/shm/firefox-$1-$USER

static=static-$FFPROFILE

link=$FFPROFILE

volatile=/dev/shm/firefox-$FFPROFILE-$USER

It does work much quicker, specially when closing down (no delay).
