@Poon05,
Although your first post states that you are using Firefox 19, the information in your last post has Firefox 18 as the browser. Your plug-ins are not the latest, and have known vulnerabilities. Your listing seems to be edited somewhat. The redirect you are receiving indicates that your computer is infected, and running a vulnerable browser and plug-ins definitely make it easy to infect.
Unless you run the programs, you ( and we ) won't know what the problems are. A lot of malware hides itself quite well.
