So after FF 31, with latest private tab update, i cant get into PRIVATE MODE, so your addon is useless now.
I removed the addon, installed it again, but to no avail.
Firefox default private WINDOW works flawlessly.
This is most likely conflict with some another extension (like https://github.com/Infocatcher/Private_Tab/issues/110 or something similar).
So, please try on new Firefox profile (to ensure, that this is some conflict):

And please also provide information from about:support page.
