Why is Firefox 57 reporting to some websites it is in Private Mode even when it isn't??

Attempts to view my local Walmart flyer from Walmart.ca have ended in screams. It seems Walmart thinks the browser is in Private Mode and/or has an ad-blocker installed. Funny thing is, FF56 loads the page just fine even WITH an ad-blocker installed. Tried it with FF56 again, and sure enough it's the Private Mode problem. FF57 appears to be reporting to the website that it is Private browsing even when it isn't.

Firefox has built-in Tracking Protection, to help speed up website loads times and protect your privacy. In Firefox 57 it's turned on by default (whereas in Firefox 56 it was only turned on in Private Browsing).

It's a shame that Walmart's website isn't playing nicely. You could disable Tracking Protection on Walmart's site using the instructions in this article (scroll down to "Turn off Tracking Protection for individual sites").
