I have a very old bootable Edubuntu image that is used at my work place. The ISO is specifically locked down to allow only two things to happen: Run Firefox (to a specific location only), and Open Office. I have made an ISO from this bootable disk, and now I need to edit it, to remove Firefox from the image, and then remake the disk. I have tried to use ISO Master, but I can't figure out how to remove this from the files that are displayed when opening the ISO in the program. I think I need to edit the squashfs, but I am very unsure of this. My Ubuntu knowledge is very limited (as you can probably tell by my description of the issue).
