title: TAB completion does not work in Jupyter Notebook but fine in iPython terminal
body: <p>TAB completion works fine in iPython terminal, but not in Firefox browser. </p>
  
  <p>So far I had tried but failed,</p>
  
  <p>1). run a command <code>$ sudo easy_install readline</code>, </p>
  
  <p>then the .egg file was wrote in <code>/usr/local/lib/python2.7/dist-packages/readline-6.2.4.1-py2.7-linux-x86_64.egg,</code></p>
  
  <p>but TAB completion still doesn't work in Jupyter Notebook.</p>
  
  <p>2). also tried to find locate the <code>ipython_notebook_config.py or  ipython_config.py</code>, but failed.</p>
  
  <p>I use Python 3.5 and iPython 4.0.0.  and both are installed in Ubuntu 15.10  <code>/usr/share/anaconda3/bin/ipython</code>.</p>
  
  <p>Any help would be appreciated!</p>
