Missing features on first-time launch in esr91

Tor Browser 11.0a9 seems to be missing key features on initial launch after a clean install, including (but probably not limited to):

• The torconnect buttons: esr91-mac-torconnect-buttons-bug
• about:preferences#tor: esr91-mac-tor-settings-bug
• new-identity functionality: esr91-mac-new-identity-bug

The bug appears to clear itself after restarting the app, and everything works as expected. Sometimes it requires multiple restarts.
