Boot from RAM and firefox doesn't run

[tenmoi]

Hello,

I followed the instruction here: http://ubuntuforums.org/showthread.php?t=707230&page=2

And Ubuntu successfully boots from RAM. The problem now is I cannot run firefox. A pop-up menu shows up saying to the effect that firefox is running and I must stop the process or restart Ubuntu.

What have I done wrong?

P.S. DHCP doesn't work either. I must add an IP manually, after which I can ping google fine.

My machine info:

uname -ra
Linux precise-x64 3.2.0-25-generic #40-Ubuntu SMP Wed May 23 20:30:51 UTC 2012 x86_64 x86_64 x86_64 GNU/Linux

Dell R N5110, Nvidia 525M, 8G of RAM.

Thank you

you might note that lot of changes have been applied since 2008 ;)

i suppose that linux (ubuntu) does not like those things running into ram due to security issue.
