This is about how to get the NAI Global Privacy Control Signal extension for Google Chrome working. I ran into something that got me a little confused while testing this extension, and will put my notes and screenshots here in case it helps others.

Here’s what you need to do.

First, visit the extension page in the Chrome Web Store.

Extension page in the Chrome Web Store

Click Add to Chrome.

Click “Add extension”

When the dialog comes up, click Add extension. You should get a message stating NAI Global Privacy Control Signal has been added to Chrome. Manage your extensions by clicking Extensions in the Tools menu.

Extension has been successfully installed

Pretty standard so far. But we’re not done! There is still one more step to actually start sending Global Privacy Control signals. Go to the GPC site and you will see GPC signal not detected at the top. To be honest, this faked me out. What I did to try to check this (that was wrong) is that I went to the three dot menu, then Extensions, then Manage Extensions, and it says that NAI Global Privacy Control Signal is On.

The extension is on but the GPC signal is still off

The tricky part is that it’s possible for the extension to be On but the GPC signal is still off. What you need to do is go to the Extensions (puzzle piece) menu, select the NAI extension…

Use the extensions menu

…then select the GLOBAL PRIVACY CONTROL (GPC) SIGNAL SETTING control and turn that on.

Flip the switch from GPC OFF to GPC ON

Once you do that, you should start to see GPC signal detected on the GPC site.

GPC on and working

Anyway, I hope this helps. Another option is the OptMeowt extension, which turns on GPC when you install it and doesn’t require the extra step.
