These two switches are really helpful for old eyes. I've set up the default font and color information I want to use in preferences / content, but I can't use this combination for all websites -- unfortunately frequently button text becomes impossible to read. With these two toggles, however, I can easily switch off my preferences and use those defined by the webpage owner.

This lets me use light font on a dark background most of the time -- it's far easier on my eyes than black on bright white! This way I only have to briefly change to the page's definitions to use its buttons.
