3rd-party filters settings page not working properly on Firefox Ultimate 64 bits #46

Hello everyone. Here are the steps to reproduce this issue:

-Install Firefox Ultimate 64 bits (latest version, grab it here: http://sourceforge.net/projects/firefoxultimate/ )
-Install uBlock₀
-Go to the Settings
-Go to the 3rd-party filters tab
-Only three filtering lists appear (My filters, uBlock filters, uBlock filters - Privacy), settings can't be remembered. This bug make uBlock₀ much less useful. This issue is also affecting uBlock, except one difference: uBlock₀ displays the message box to enter custom URLs for filtering lists and the Parse button.
