Two nights ago my MacBook Pro did a system update. When I came back to my computer in the morning and pulled up FireFox, it was black and white with not showing certain icons and text font looking weird and just all around messed up. For example, for my job's website there is none of the colors that should be there and it looks really off. For Google Sheets, I use highlights to help know where I am in a process of working but when I click on the icon to show me the highlight colors it is all white with a few white boxes. When I take the cursor to an area, it will show me a small box with what the color is and I can still click and get a color. So it is like the viewing of FireFox is messed up and I don't know how to get it back to normal. When I go to another website, like IXL.com, and try to select an answer, you can't see what has been selected and you don't see the box around "submit" to make he button image. I have uploaded my screen images of what I am talking about, including one of this support page because I have a feeling this is not how it is suppose to look.
