I have a 13" Macbook Pro running OSX 10.9.5

All of the sub menus under preferences are unreadable or unusable because they are the wrong sizes so they aren't displaying the options. I can't make many changes or adjust any of the settings. Some of the menus end up being a tiny sliver with nothing showing.

I've disabled the add ons. The only one I was using was the Theme Changer, which I installed in the hope of fixing this problem. It didn't. If anything it has made it worse.

There is a bug that I think covers this. https://bugzilla.mozilla.org/show_bug.cgi?id=1087964

The bug is fixed for versions after 49, but reading the test I think if you use the config editor to change the following preference to 1.0 then you might see a workaround.

layout.css.devPixelsPerPx=1.0

If the preference does not exist create it, and please report your results.
