The find+ preferences pop up can be too small if users use our own font size preferences. I end up with a horizontal scrollbar.
Steps to Reproduce
In Firefox, use userChrome.css and/or userContent.css to set a large font size. [The default preferences only allow a minimum font size, not a maximum, so they aren't always usable. The web extensions don't work in about: pages or Mozilla's own pages.]
