I'm getting this error while installing/listing firefox or python on a Linux server. Any ideas how to fix it.
# yum install firefox
There was a problem importing one of the Python modules
required to run yum. The error leading to this problem was:
/usr/lib64/libnssutil3.so: undefined symbol: PL_ClearArenaPool
Please install a package which provides this module, or
verify that the module is installed correctly.
It's possible that the above module doesn't match the
current version of Python, which is:
2.4.3 (#1, Oct 23 2012, 22:02:41)
[GCC 4.1.2 20080704 (Red Hat 4.1.2-54)]
If you cannot solve this problem yourself, please go to
the yum faq at:
http://wiki.linux.duke.edu/YumFaq
Instead of getting the following output/value for firefox -version command.
$ firefox --version
Mozilla Firefox 17.0.9
I'm getting:
XPCOMGlueLoad error for file /opt/firefox/libxpcom.so:
libxul.so: cannot open shared object file: No such file or directory
Couldn't load XPCOM.
python -h command output looks valid.
python -V shows:
Python 2.4.3
When I'm running Selenium tests (which requires firefox and Xvfb), I get the following error:
org.openqa.selenium.firefox.NotConnectedException: Unable to connect to host 127.0.0.1 on port 7055 after 45000 ms. Firefox console output:
XPCOMGlueLoad error for file /opt/firefox/libxpcom.so:
libxul.so: cannot open shared object file: No such file or directory
Couldn't load XPCOM.
XPCOMGlueLoad error for file /opt/firefox/libxpcom.so:
libxul.so: cannot open shared object file: No such file or directory
Couldn't load XPCOM.
The problem is not python, it’s the LD_LIBRARY_PATH that does not include /lib64 and /usr/lib64 setting values. we fixed this by pre-pending /lib64:/usr/lib64 to the LD_LIBRARY_PATH.
export LD_LIBRARY_PATH=/usr/lib64/:/lib64:$LD_LIBRARY_PATH
After this point, when I did yum help or yum install firefox (it didn't give the above error) BUT:
firefox --version still gave the error:
XPCOMGlueLoad error for file /opt/firefox/libxpcom.so:
libxul.so: cannot open shared object file: No such file or directory
Couldn't load XPCOM.
Now, I finally ran yum install firefox and it installed bunch of components and at the end said:

Complete!
Now firefox version is showing correctly.
firefox --version
Mozilla Firefox 17.0.9
Everything is working now.
