FF 46.0.1 BPO Jessie: Menu Entries and Contexts Black on Black with default theme

[Wolfgang Schnitker]

Dear Maintainers,

I just got FF 46.0.1 from BPO on my Jessie system.

After this update all Menu Entries and Context Menus are illegible
because of black background and black font.

Tried in safe mode.

Tried to disable HW Acceleration even in safe mode

Tried all things from Google about this topic in all versions.

Solution: Install full theme Walnut 2 from Add-Ons, works.


Regards

Wolfgang
