Bad idea? Editing a multi boot disc in ultraiso

[andyd]

I'm pretty much done with my disk but need to get firefox to work in ERD. I was kinda following the instructions in the other thread but the cd ceases to function by using one of the commands. I really rather not spend any more time trying to get it to work as I've spent so much time already getting this disc to where I want it to be.

Can I now just edit the disc and copy in the firefox folders? What options do I have to set in this?

Nevermind...worked it out myself
