Embedded Web Browser other than JDIC

Good Day. May I ask if there are other API that I can use to embed a Web Browser in Java. I've already tried using JDIC and had some problems with it. It needs IE to be set as the default browser since it does not support Firefox. Also there is an instance that I visited a site where the language option is done in pop-up, and after I chose the language, the site does not change. I think, it has some problem with pop-ups. So I'm looking for other options. Thanks in advance.
