Thunderbird upgraded to the new version, but it didn't work - arrows did nothing, trying to go to settings said "TypeError: FPVSOptions.prefs.prefs is undefined".

Issue #26 on Github https://github.com/Extended-Thunder/folder-pane-view-switcher/issues/26 gave a workaround:

1. Removed the add-on
2. Restarted TB
3. Searched for add-on through extensions page in app
4. Loaded add-on
5. Works!

and that seems to work for me. Very happy this extension is working again.
