Always apply Do Not Track is selected but PANOPTICLICK shows that Do Not Track is off. How do I fix this?

more options

When I test my browser on https://panopticlick.eff.org the results show that the browser is *not* accepting Do Not Track commitments. I tried this using a regular window and privacy window. I don't why that is since under Options>Privacy>manage your Do Not Track settings, I have "Always apply Do Not Track" checked.

PANOPTICLICK is able to see my other privacy settings on my browser, however. I'm assuming their test results are correct.

Please, help me resolve this.

Note that the DNT setting that Firefox uses is under the fingerprint details (DNT Header Enabled?). Do not get confused by the item about a website that promises to honor DNT that shows at the top. Firefox always sends a DNT header when enabled.

I'm not sure what that means, that Firefox would "accept" a "commitment" from the site to honor Do Not Track. The commitment page appears to be a text file or HTML document. Would you want Firefox to display it or try to interpret its meaning? This seems like maybe a feature for future consideration rather than something critical now when most sites don't even pay attention to the Do Not Track signal.
