Capturing HTTPS traffic of application

I want to use Charles/Fiddler to capture HTTPS traffic from application.

After installing trusted root certificate I've noticed that not every application will accept it. For example, I can intercept all requests made by Chrome, but on Firefox I need to add trusted certificate.

When capturing traffic for Java application, certificate need to be added to JVM TrustStore, and in case of using Python script we need to add line of code that use exported certificate.

How can I analyze requests made by some software that support proxy (so reverse proxy can be easily used), but after running it I cannot get plaintext as it needs trusted certificate?
