Debian (Wheezy) 安装 firefox 21 （64bit）

参考以上帖子，不过有两几个地方可能需要调整
1、下载路径：

2、图标的路径有问题，需要修改：

sudo ln -s /opt/firefox/browsers/icons/mozicon128.png /usr/share/icons/hicolor/128x128/apps/firefox.png
sudo ln -s /opt/firefox/browsers/icons/mozicon128.png /usr/share/pixmaps/firefox.png

原文摘抄如下：

    Download Firefox

    Download latest version of the original Mozilla Firefox for Linux from the official Mozilla website here, and put it in the Downloads folder within your Home directory (/home/YourUserName/Downloads).
    .
    Install Firefox
        Copy and extract Firefox archive
        Open Terminal, and change directory (cd) to the Downloads folder:

        Then run the following commands (one-by-one):

            sudo cp firefox-*.tar.bz2 /opt
            cd /opt
            sudo tar -xvf firefox-*.tar.bz2
            sudo rm firefox-*.tar.bz2

        Create symbolic link to firefox binary
        Backup (move) any existing firefox bin:

            sudo mv /usr/bin/firefox /usr/bin/firefox.backup

        Create symbolic link to the real firefox binary:

            sudo ln -s /opt/firefox/firefox /usr/bin/firefox

        sudo ln -s /opt/firefox/icons/mozicon128.png /usr/share/icons/hicolor/128x128/apps/firefox.png

        sudo ln -s /opt/firefox/icons/mozicon128.png /usr/share/pixmaps/firefox.png

        Create firefox.desktop file in /usr/share/applications
        Open gedit (or another text editor app) with root privilege:

            gksu gedit /usr/share/applications/firefox.desktop

        Then copy-paste the following text:
