Wurscht.
Habe folgendes gefunden und es funzt:
... I would suggest you type
about:config in the addressbar (note, that there are no spaces in that) and search for
ipc in the searchbox at the top of the about
:config page.
Right click those top 5 entries and
toggle them to the opposite of what they are now, i.e.
dom.ipc.plugins.enabled.npswf32.dll - true becomes...
dom.ipc.plugins.enabled.npswf32.dll -
false ...and so on...
That will disable all the container stuff and you should be good to go.
