Need to use a program using the URL chrome://espdesktop/content/desktop.xul. To do this I had to install a file into the chrome subfolder.How can I do this?

I am trying to use the ESP program, an older research program that uses the URL,

chrome://espdesktop/content/desktop.xul. To get this to run, you are supposed to create a "chrome" folder that includes the text file "installed-chrome.txt" that includes the following directions: content,install,url,file:///c:/Program%20Files/esp4/

However, this does not seem to work with the newer version of Firefox. Is there anyway to work around this? I tried just creating a folder called "chrome" with these instructions in C:\Program Files (x86)\Mozilla Firefox\chrome but it did not work. Do you have any suggestions?

Thank you. I tried that by putting the "chrome" folder that I made into the browser folder but it did not work. Any other thoughts?

With what Firefox version did this still work?

I'm seeing some references to the installed-chrome.txt files in the Firefox 10esr code, but not in later versions.

In later versions, including the current release it only shows in the removed files list.
