Linux ubuntu 18.04 - Libreoffice 6.0
Firefox has changed the way they made key for digital signature since 2018. So the key are not accepted by libreoffice any more. Fortunately, I can use old key from old version of firefox or use palemoon (another form of firefox based on old firefox - https://www.palemoon.org/) to make my key.
Why Libreoffice don’t upgrade to accept the new key ?
