I downloaded Firefox (firefox-15.0.1.tar.bz2) file from this link
Now That file is present under /opt directory, this is the permission of that file
-rw-r--r-- 1 root root 19280364 Sep 17 15:33 firefox-15.0.1.tar.bz2
I extracted that file using this command
tar -jvxf firefox-15.0.1.tar.bz2
now the extracted file present in Firefox directory (under /opt)
Inside Firefox directory one script is there run-mozilla.sh, this is permission of that script
-rwxr-xr-x 1 root root 8915 Sep 6 04:52 run-mozilla.sh
I tried this command to execute that script
sh run-mozilla.sh but it's showing this error
[root@localhost firefox]# sh run-mozilla.sh run-mozilla.sh: Cannot execute .
I thought that it's a installation script...
Now what should I do, why its showing that error?
I am using CentOS 6.2


sudo yum update; sudo yum install firefoxshould give you Firefox 10.0.5, installed and ready to go. – Eroen Sep 17 '12 at 12:27
