On Windows 7 with Firefox 52.0 I get only the bottom half of summation symbols displayed.
As an example, I provide a small screenshot below the following link. Does anyone know what I need to do to get summations to display correctly?

Per the OP'S Comment, experimenting with the various Math Renderer options in the right-click MathJax menu resolved this problem satisfactorily.
Choosing among the Math Renderer options is made by cookies on a site by site basis. Thus I can have different options for Math.SE, Meta.Math.SE, and SciComp.SE.
Some renderers are more robust and others faster in keeping up during lengthy Edit sessions, so prolific Users are helped by these menu choices.
