Why do I see red boxes on websites?

What are the red boxes I see?

If you are seeing red or pink boxes on a webpage, this is the result of enabling Turn on debug element hiding filters mode on the Advanced tab in ABP's Options.

So that you can see what's hidden on a webpage, the debug element hiding filters mode highlights in red any elements that are affected by element hiding filters. Here's an example:
