Tor Browser does not apply a certificate
When the user tries to import a certificate .der by using Tor Browser -> Preferences -> Privacy and Security -> View Certificates... -> on tab "Authorities" click on "Import...", -> select the .der file, click on "Trust this CA to identify websites" and then click on OK, restart Tor Browser.
Reopening Tor Browser and going to Tor Browser -> Preferences -> Privacy and Security -> View Certificates... -> tab "Authorities", the CA related to the .der file does not appear.
The test file has been cacert.der file of PortSwigger CA. Source: https://portswigger.net/burp/documentation/desktop/getting-started/proxy-setup/certificate/firefox
