Maybe it's the ad blocker

I'm normally a very patient person when it comes to a lot of things. I don't mind ads very much except when they randomly hijack large portions of a page. I have unlimited data on my mobile phone so I'm not worried about exceeding data allotments or bandwidth and I have no issues with ads showing on my home computer.

At work, however, I don't like seeing ads at all because they can easily be inappropriate and they just get in the way. Unfortunately, tech sites often have very many ads, so I have an ad blocker installed.

In one situation however, we were looking at why a section of a site we are supporting was missing in all browsers except IE. Obviously the cause was the ad blocker plugin (this is the theme of the post).

We looked into the CSS and Chrome developer tools to see what might be causing it to be hidden. There was a large grayed out section of styling with the following:

display: none;
visibility: hidden;
orphan: 4321;

This block was added by the AdBlock plugin on Chrome. If you're missing some code from your project and you see this, try disabling your ad blocker.
