I have a problem with Launching firefox from quick launch bar after update on CentOS. It just didn't work. But I can launch it in terminal by typing:~$: firefox
I updated firefox by doing works below:
yum remove firefox wget http://download.firefox.com.cn/releases/firefox/9.0/en-US/Firefox-latest.tar.bz2 tar jxvf firefox*.tar.bz2 mv firefox /usr/local ln -s /usr/local/firefox/firefox /usr/bin/ /usr/sbin
