Stop Warning Me About Popups
Don't grey out the whole screen with a warning that I'm blocking pop-ups until I acknowledge it. Then don't do it again every single time. I get it, my browser blocks pop-ups. I set it that way years ago because the internet is unusable otherwise and things worked fine without them last semester. Put a unobtrusive note in the corner if you need to. The warning itself is actually interfering with my ability to use it.
