The main menu shortcuts Alt + C (Customize) and Alt + S (Setup) now suppress the reaction of the browser to these key combinations, so that they reliably open the corresponding main menu.

Before, Firefox could act on them first and, for example, open its browsing history or move the focus into the address bar instead of opening the menu.

This only affects Firefox, and only with certain interface languages, since Firefox derives these key combinations from its localized menu labels. In all other browsers, and in Firefox with other languages, Alt + C and Alt + S are not assigned to any browser function. No other keyboard shortcut is changed.
