Greetings

I'm trying to deploy firefox in spanish using policies.json and this is the code im using:

{

 "policies": {
   "Extensions": {
     "Install": ["/usr/lib64/firefox/distribution/extensions/langpack-es-MX@firefox.mozilla.org.xpi"],
     "Uninstall": [],
     "Locked":  []
   }
 }

}

Whenever i launch firefox, the langpack is not installed, the "about:policies" page display the following error:

Download failed - ERROR_NETWORK_FAILURE - file:///usr/lib64/firefox/distribution/extensions/langpack-es-MX@firefox.mozilla.org.xpi

We always put the folder of the language pack in /firefox/browser/extensions/ but after upgrading to firefox 76 is not working, i can install manually the langpack but that's not an option. Is there is something wrong with my code?

Sorry for my broken english.

Thank you

I tried to load the extension in the web browser and you were right there is an filesystem error.

I changed the location of the extension and the about: policies doesn't show any errors. After I restarted the browser the UI was in Spanish.

Although I would like the end user didn't have to restart the browser every time, maybe if I play with some of the extensionsettings in the policies.json files.

It sounds like we can't access the file for some reason. What happens if you put

file:///usr/lib64/firefox/distribution/extensions/langpack-es-MX@firefox.mozilla.org.xpi

in the URL bar?

does it load the XPI?
