Where do I find the libxul.so library for my Linux system?
<p>I recently downloaded the 64-bit version of Firefox for my Linux system …</p>

<pre><code>[davea@mydevbox mydir]$ uname -a
Linux mydevbox.mydomain.com 7.3.8-25.26.amzn1.x86_64 #1 SMP Wed Mar 16 17:15:34 UTC 2016 x86_64 x86_64 x86_64 GNU/Linux
</code></pre>

<p>but I don’t seem to be able to run it, getting this bizarre error …</p>

<pre><code>[davea@mydevbox firefox]$ ./firefox -V
XPCOMGlueLoad error for file /home/davea/firefox/libxpcom.so:
libxul.so: cannot open shared object file: No such file or directory
Couldn't load XPCOM.
</code></pre>

<p>Does anyone know what library I need to install to get “libxul.so”?  I tried “yum install libxml” but that didn’t resolve to anything.</p>
