Mozilla Apps Enhancements

Hello everyone

lately when I am trying to use Mozilla Apps Enhancements addon with Mozilla Thunderbird

https://addons.nvda-project.org/addons/mozillaScripts.en.html

The keyboard shortcut for opening menu options for a contact is not working

out of list  • In a message window:

list  with 4 items  • Control+Shift+(1-4) Reads the sender and recipients of the message. If pressed twice quickly, opens the options menu.

Am I missing something or this is an you issue that needs to be fixed

Thanks in advance

Eilana
