I just installed the latest FF version (20220308) on a 13 'Mac Book Pro with Monterey 12.3.
I note that:

1. in the Preferences menu it is impossible to select the menu items, both the pull-down menus and the on / off buttons.
2. The same situation for many other checkboxes. For example, Show -- Show H. Metrics, where options cannot be set.
   Thank you for your attention
