title: Firefox and Chrome inconsistently crashing all the time - seems related to gstreamer
body: <p>I'um using RHEL 6.7. My Firefox suddenly started crashing over and over again at the most random times possible. <strong>The only real consistent crash I noticed is when I enable desktop notifications on Slack</strong>.</p>
  
  <p>The console shows this when Firefox crashes:</p>
  
  <pre><code>###!!! ABORT: Aborting on channel error.: file /builds/slave/rel-m-rel-l64_bld-000000000000/build/ipc/glue/MessageChannel.cpp, line 1584
  </code></pre>
  
  <p>I looked for the error message online and many people reported that <code>gstreamer</code> is the problem. I tried reinstalling some of my gstreamer plug-ins, but with no success.</p>
  
  <p>I then switched to Chrome and the same thing started happening... :( I keep getting the "Aw, snap" page. This is really impacting my work.</p>
  
  <p>I have several colleagues with my same laptop, same browser version, same OS, same kernel... everything! They don't get the same issue.</p>
  
  <p>I'm assuming other people have been through the same and possibly I haven't fixed gstreamer properly. Any thoughts?</p>
