want to use old research program that worked through firefox chrome folder via modification of installed-chrome.txt file
there is a program (ESP, the Experience Sampling Program) that allows easy development and installation of research protocols via palm pilots. The program runs in mozilla-based browsers--Mozilla or Firefox. After the program is installed, it is accessed by hitting the URL chrome://espdesktop/content/desktop.xul. Previously, this required editing the file "installed-chrome.txt" file which was located into the chrome subfolder. The newest versions of firefox have done away with this subfolder. Not being a programmer, I am having trouble figuring out how to access the program now.

First thing I noticed is you are running on an outdated/older version of Firefox & not the current version. Download it from here:
- At the top of the Firefox window click the Firefox button, go over to the Help menu and select About Firefox. For Windows XP: Go to the Help menu and select About Firefox.
- The About Firefox window will open and Firefox will begin checking for updates. If updates are available, they will begin downloading automatically. If Firefox is already up to date, just close the About Firefox window.
- When the updates are downloaded and ready to be installed, click Restart to Update. Firefox will be restarted and the updates will be installed.
If the extension is still packed and you have the XPI file then you will have to open that XPI file which is a ZIP archive and edit that file. Most archive managers allow to edit and update the file directly from within the archive without the need to unpack the XPI file.
The newest versions of firefox have done away with this subfolder.
You can create that folder yourself, or install the ChromEdit Plus extension which will create that folder for you.

Sounds like that ESP, the Experience Sampling Program, hasn't been updated in the last couple of years, so I doubt if it is "packed" . IIRC, the "chrome" folder was removed from Firefox as far back as Firefox 4 or 5. But Firefox does work as it previously did when the user creates that folder in the Profile folder.
