Package: firefox-esr Version: 68.12.0esr When you want to add a client-certificate, you go to about:preferences | privacy and security | show certificates-button
Then the certificate manager window opens, and you have to go to the "your certificates" tab. The default size from this window is too small, you don't see the "import" button. Only if you resize the window you see the button. -- Paul van der Vlis Linux systeembeheer Groningen https://www.vandervlis.nl/
