Whenever I have the Thunderbird screen in focus and use alt tab to change windows something strange happens. The alt tab function is disabled (no longer works) and this behaviour can only be rectified by a reboot. I think this is a bug with Thunderbird. I am using Ubuntu 21.10
Where should I report this? Is this issue specific to Ubuntu 21.10 or should the Thunderbird people be informed?
restart
, rather than a complete reboot.
