It took me a while to figure out how to make the AppContainer sandbox functional again between Firefox 118-119 releases. It ended up being an additional Utility process (Oracle JavaScript) that was causing the failure. The trigger for that utility process was the obscure user_pref browser.opaqueResponseBlocking.javascriptValidator that took some time to track down. After disabling that, Firefox LPAC sandbox is working once again.

  • updated Firefox binaries to 119.0.0
  • updated user.js (Firefox 118+: Disable Utility process for Oracle JavaScript) to prevent crash
  • updated user.js (Disable Picture-in-Picture) to avoid crash
