I was looking for a Tiny Core image with Firefox preinstalled, found this spartan web page: Marketplace – Firefox – GNS3
That has a hidden gem in it: http://downloads.sourceforge.net/project/gns-3/Qemu%20Appliances/linux-tinycore-linux-6.4-firefox-33.1.1-2.img
A bootable image with a pretty recent web browser.
It’s always useful.
