I deinstalled the "Night Mode Pro" plug in.
I just could not figure out how to make the hyperlinks appear in "night" mode. They are there, but the plug-in seems to invert all the colors on a page EXCEPT the hyperlinks. Which if you say want to upload a picture, is a bit hard to do if you don't remember exactly where they are (they appear if you hover over them).
If I ever get it figured out, I'll post back.
