XPCOMGlueLoad error for file /usr/lib64/firefox/libxul.so:
libXt.so.6: cannot open shared object file: No such file or directory
Couldn't load XPCOM.

Solution:

yum install libXt*  Install the appropriate packages
rpm -qa | grep libXt View the installed packages and see if the number is complete.

Note: you can’t use RPM - uvh libxt * to install. This installation method will report package dependency errors, even if you install interdependent packages together. The reason is that RPM does not solve the problem of package dependency
