Firefox ESR 128.x upgrade broken ?
My organization has been using Firefox ESR for many years. I am trying to upgrade from ESR 115.12 to ESR 128.1 The upgrade is hanging at the very end of the install. Procmon shows firefox.exe being launched in the background and hanging. When I manually run firefox.exe, it says "Unable to read configuration file". If I edit "autoconfig.js", and comment out the "general.config.filename", then everything works.
We still use the general.config.filename and have not fully transitioned to the newer policies.json configuration (we have settings in both).
Was a change made in ESR 128 that broke (or stopped supporting) the older format ?
thanks, -stephen

You can check the Browser Console for more info about what is wrong with the autoconfig.cfg file.
- https://firefox-source-docs.mozilla.org/devtools-user/browser_console/
- https://support.mozilla.org/en-US/kb/customizing-firefox-using-autoconfig

The autoconfig.cfg file is run as a JavaScript file and errors in the file throw an exception. Note that the update to 128 ESR is not yet done automatically, as there is an overlap of two versions (i.e. the switch would happen with 128.3.0).
