哪位好心的哥哥姐姐来帮忙啊`

下载了Thunderbird1.5 RC2 的版本，也解压缩了，就是不知道怎么运行……在Ubuntu社区问怕太丢人了，这里都是自己人，就随便问了    

目录内容：

chen@ubuntu:~/download/thunderbird$ ls

我试乐一番，没成功

chen@ubuntu:~/download/thunderbird$ sudo chmod +x thubderbird

不好意思，是我的电脑太慢了，在Konqueror里双击了thunderbird的脚本没反映，谁知道我上面的帖子发完了，TB终于开始运行了    

昏，ubuntu应该速度还是不错的啊．

楼主机子啥配置？？？

难道比我还牛？？？

传说中的286原型机？

难道是龙芯二号？

PIII 500 + 320M 内存呀
