I'm trying to build a modified firefox.

Can you please teach me how to do this?!

I solved the case!
Before creating "ezremaster" iso
make the application the final you want it to be!
(The application must be closed, otherwise there may be a possibility of an incomplete copy problem due to file usage!)
live "home" directory content
Copy it into the "home" content that ezremaster created!

then press create iso with ezremaster!
After burning the iso file to sd or usb
to the "onboot.lst" file in the "cde" folder
firefox.tcz
add the line

apps-->maintenance-->onboot

I don't know if there is a user manual about it!?
but can you make a guide article about it?
