I installed Mozilla Firefox version 3 today. I have used Mozilla Firefox version 2 for my PC browser. However, they've announced the version 2 will be no longer updated so I thought I had to start to use the version 3. To tell the truth, I didn't want to install the version 3 because I got a trouble when I installed it before. I hope I will not have the same trouble this time. I haven't made sure of it yet. So far, my recent bookmarks are missing and there isn't a button for move to back and forth in the tool bar. I am disappointed at it.
