系统：debian6.0.4
我这样安装了火狐
1.下载
Download latest Firefox from: http://www.mozilla.com
2.解压后放置在/opt
3.创建链接
$ ln -s /opt/firefox/firefox /usr/bin/firefox

安装完成后，存在的问题
1.每次只能在root 下面用/usr/bin/firefox启动
2.启动后出现

An error occurred while loading or saving configuration information for firefox. Some of your configuration settings may not work properly

Failed to contact configuration server; the most common cause is a missing or misconfigured D-Bus session bus daemon. See http://projects.gnome.org/gconf/ for information. (Details - 1: Failed to get connection to session: Did not receive a reply. Possible causes include: the remote application did not send a reply, the message bus security policy blocked the reply, the reply timeout expired, or the network connection was broken.)

请问，如何解决问题？
1.我的电脑里面有两个组，要求任何用户组（包括root）都可以启动它
2.不出现那样的出错信息。

发现一个奇怪的事情，如果我将firefox安装在/usr/lib目录下面，不是
/opt目录下面，就不会有任何问题，上面的两个问题都不存在。
cp ～/firefox-12.0.tar.bz2 /usr/lib
cd /usr/lib
tar -jxvf firefox-12.0.tar.bz2
ln -s /usr/lib/firefox/firefox /usr/bin/firefox

我的电脑里面有两个组，要求任何用户组（包括root）都可以启动它

0. mysudoer 表示你安裝 ubuntu 的登入帳號
1. 創造一個 group 例如 myfirefox
2. 把你希望能夠使用 firefox 到 用戶 都加到 myfirefox 名單中 # （包括root）
3. sudo chown mysudoer:myfirefox -hR /opt/firefox
4. sudo chmod -R 775 /opt/firefox # myfirefox 以外的人 可以打開但是不能更改
5. sudo chmod -R 770 /opt/firefox # myfirefox 以外的人 不可以打開

如果我将firefox安装在/usr/lib目录下面，不是
/opt目录下面，就不会有任何问题，上面的两个问题都不存在。

比對權限
sudo ls -al / | grep opt
sudo ls -al /opt | grep firefox
sudo ls -al / | grep usr
sudo ls -al /usr | grep lib
sudo ls -al /usr/lib | grep firefox

还发现一个问题，如果将firefox安装在/usr/lib下面，在root状态使用
firefox命令调用火狐浏览器，出现同样的故障：


(firefox:6158): GnomeUI-WARNING **: While connecting to session manager:
None of the authentication protocols specified are supported.

如果我将firefox安装在/usr/lib下面，在root状态下，使用火狐，如何使他不出现这些错误输出呢？

方法同 #3

tiger@debian:~$ /opt/firefox/firefox
bash: /opt/firefox/firefox: Permission denied
tiger@debian:~$

明明对其他任何用户都有执行的权力，我让它运行的时候，为何禁止了？
-rwxr-xr-x 1 root root 54008 Apr 20 18:59 firefox

還要看 tiger
sudo ls -al / | grep opt
sudo ls -al /opt | grep firefox
有沒有 x 權限

如果沒有 tiger 就不可能去 接觸
/opt/firefox/firefox

tiger@debian:~$ sudo ls -al / | grep opt
drwxr-xr-x 4 root root 4096 May 25 08:49 opt
tiger@debian:~$ sudo ls -al /opt | grep firefox
drwxr-x--- 10 root root 4096 Apr 20 18:59 firefox

sudo ls -al /opt | grep firefox
drwxr-x--- 10 root root 4096 Apr 20 18:59
firefox

sudo chmod 755 /opt/firefox

3. sudo chown mysudoer:myfirefox -hR /opt/firefox
4. sudo chmod -R 775 /opt/firefox # myfirefox 以外的人 可以打開但是不能更改

为何还要第3句？感觉不要它也可以，第4句不是让任何人都执行吗？
