You could use sdmem.

sudo apt-get install secure-delete


To make it run at every shutdown, we'll create an Upstart job file called memory_wipe.conf.

Note: this is one command. Copy/paste it in its entirety!

echo '# upstart config - wipes memory on shutdown

description  "Wipes memory on shutdown"

start on (runlevel [016] and stopped gdm)

script
    sdmem
end script' &gt; sudo tee /etc/init/memory_wipe.conf


Restart your computer and upon the next reboot, your RAM will be wiped securely!

How to wipe RAM on shutdown (prevent Cold Boot Attacks)?
I like to group my bookmarks into Folders in the Bookmark Bar.

But I cannot find an easy way to delete these bookmarks!

The only way I know to do this is to go to Show All Bookmarks, then browse down to the shortcut and select it and delete it - this totally gets in the way of workflow.

Is there any way to delete a Foldered bookmark from the bookmark bar?!

NB - I am not talking about standalone bookmarks, deleting those is easy and intuitive.
