My original intent was to customize firefox with userChrome.js scripts. However /defaults/pref directory is nowhere to be found.

Tested on both apple silicone and intel macs running macos sequoia 15.3, firefox 135.

Custom userChrome.css files are in use but I don't think it matters.

I did use browser console to find and recheck file directories. Going through every folder in both firefox.app/contents and /Users/(myname)/Library/Application Support/Firefox/ showed nothing.

Show hidden files are turned on, and the following commands via terminal showed no valid responses.

sudo open /Applications/Firefox.app/Contents/Resources/defaults/pref

open /Applications/Firefox.app/Contents/Resources/defaults/pref

cd /Applications/Firefox.app/Contents/Resources ls -la cd defaults ls -la cd pref ls -la

find /Applications/Firefox.app -name "pref" 2>/dev/null

I need assistance with updating an old version of Firefox installed in the local AppData folder on our users' machines. We currently use Intune for application management, but I'm unsure how to remove the user-based installation and revert to a system installation without losing bookmarks.

Could you please provide guidance on how to:

1. Numbered list item Force update Firefox to the latest version while keeping user data intact.

2. Remove the user-installed version of Firefox using Intune.

3. Ensure that bookmarks are preserved during the update process.

Thank you for your help!
