ProPublica 1.6.15 extension content does not fit window when in overflow menu

When launched from the overflow menu, the content area is both wider and shorter than the window:

It is still usable, but it's difficult to see the buttons on the top ad, and requires horizontal scrolling to read the full ad text.

@rhelmer Thanks for reporting this. That's a surprise to me. What version of Firefox are you using, and on what platform? (Also, that banner that says "Facebook Political Ad Collector" doesn't look familiar.)
