Just had another thought regarding this problem!

The left two screens are managed by nVidia whilst the right-hand [laptop] screen is Intel HD.

However, no other applications seem to be suffering with the problem so far - only Firefox.

Could you type about:support and copy here the section "graphics".

Does it work if you disable HWA in Firefox?

I've a work around for the problem too!

If I create a new tab in the blank window (<Ctrl>+t) then I can *drag* the first tab out of the blank window and its all good!

Comment 6

[github.guy]

It *does* look to be related to HW acceleration!

I'm sure that I tried previously, but maybe I didn't do a full FF restart.

So, WITHOUT HW acceleration looks like it free from this issue - which ties in nicely with the split video HW support Intel for the laptop screen vs nVidia for the [larger] Display Port attached screens.

IMHO, you should update your drivers, especially with Win 10. Both drivers (Nvidia and Intel) are pre-anniversary update for Win 10and are known to be buggy.
