This needs triage to pick a correct component, but Fx::General is definitely wrong.

I can reproduce this problem with Fx45.0 in Lubuntu 14.04.4 LTS, WFM in Fx46.0b11 & 44.0.2 on Win10. Obviously it's not a layout problem, like a interoperability issue. I see this font size option has been unchecked when the problem occurred, as well as no error message in Web Console.

*Removed the "Obviously", do not rule out this possibility for particular case.
