Answer 1

You can configure your Java application to use Charles in code or as command line arguments to the java executable.

System.setProperty("http.proxyHost", "127.0.0.1"); System.setProperty("http.proxyPort", "8888");

And for HTTPS as well. Note that you may also want to configure Java to trust Charles's root certificate in this case (see SSL Proxying).

System.setProperty("https.proxyHost", "127.0.0.1"); System.setProperty("https.proxyPort", "8888");

Answer 2

proxy settings for Firefox are stored in prefs.js file of user

%APPDATA%\\Mozilla\\Firefox\\Profiles\\7a3fd5zw.default\\prefs.js

here 7a3fd5zw is a random string. There are settings named "network.proxy.http" and "network.proxy.http_port".

May be, you can try to modify them.
