[IPython-dev] IPython 2.0.0 -- Firefox issues

[Angelika Schneider]

I have the same problem with Firefox (on Mac, Redhat 5.8 and CentOS 6.5) and
IPython 2.0:

* "ipython notebook" launches the dashboard in Firefox as expected
* "New notebook" creates a new notebook and opens a tab for it, but the page
is blank and the notebook does not show up as "running"
* Opening an existing notebook also yields only a blank page, and the
notebook does not show up as "running"
* No error messages in the terminal window, but the Web Console reports "
SecurityError: The operation is insecure"
* Launching Firefox in safe mode (with all add-ons disabled) does not fix
the problem, creating a new profile does.

After some debugging, I found that the problem is caused by changing  the
cookie preference "Keep until:" " they expire"  to "ask me every time" (in
Preferences->Privacy->History). As soon as I switch  to "they expire" or "I
close Firefox" and reload the page with my notebook, it renders as expected
and the notebook is shown as running. Creating new notebooks works also
correctly.
