I hit this bug too with firefox 94.0.1-1 / Ubuntu 20.04.3 LTS (Focal Fossa)
when trying to import my certificate from /etc/ssl/certs/toto.crt, that has previously been installed with update-ca-certificates, "nothing happens" as you describe when opening the Browser Console, and repeating the action, I get an error: message: "Component returned failure code: 0x80520012 (NS_ERROR_FILE_NOT_FOUND) [nsIX509CertDB.importCertsFromFile]" we can see what happens by looking in the snap: snap run --shell firefox cat /etc/ssl/certs/toto.crt : No such file or directory this is a symlink that points to a folder under /usr/local/share/ca- certificates which is not accessible by the snap. Fix it: copy the file under $HOME where it can be imported... hth -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1913570 Title: Firefox not opening file chooser dialog for importing certificates To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/firefox/+bug/1913570/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
