Hi:
I am running FF46 on a ubuntu machine. And I noticed that the addon panel, as well as firefox’s own ‘open menu’ panel showed at the wrong position once I resize/move the browser window. The position seems to be where the toggleButton was at before the resize/move (see attachment).
The most recent nightly build (49.0a1) has the same problem, but 45.0a does not, so I assume this is a new bug. BTW, my colleagues saw the same problem on their linux FF46. Anyone has an idea of what is going on?
Thanks
