同上,参见 :http://www.aptana.com/docs/index.php/Installing_the_IE_debugger Aptana Studio 2.0 debug 调试问题2009-12-02 11:18Aptana 2.0 报这个错 launching firefox - internal server has encountered a problem 然后第一次debug跳到 http://www.aptana.com/?debugger=true&port=3726 第二次debug:也是一个 Aptana Firefox extension launching...please wait. 然后会报错: Socket connection error. Please try shutting down and restarting your web browser, and then run 'debug' again. Accept timed out 搞来搞去,结果是firefox版本问题,把原来的3.5.5换为3.5就没问题了。
