Bug#864272: firefox-esr: Login to cups server does not work with umlaut in the password

[Max Kubierschky]

Source: firefox-esr
Severity: normal
Tags: upstream

Dear Maintainer,

I cannot login to the cups server with firefox, when the password contains umlauts

reproducing the bug:

* Use german installation of debian 8
* Install firefox-esr and cups
* Add user cupsys, choose password with umlaut
* Point firefox to http://localhost:631/admin
* Try to add printer (or any other admin option)
* Cups will ask for authentication. Try to log in as cupsys
* Cups will not accept the password

Yours,
Max
