Hi greenmanharper, when sites discover that part of their content is blocked, they are quick to blame an ad blocker because they are a popular type of add-on. They don't actually have access to your Firefox extensions list or settings.

Firefox has one built-in feature which has effects similar to an ad blocker or privacy add-on, and that is Tracking Protection. When some content in a page is blocked by that feature, a "shield" icon appear toward the left end of the address bar (near the i-in-a-circle or lock icon). You can click that to reload the page without blocking trackers and see whether the site is restored to full functionality.

More info: What happened to Tracking Protection?.

And of course if you have any extensions like Adblock Plus, Blur, Disconnect, Ghostery, NoScript, Privacy Badger, uBlock Origin or uMatrix, check their toolbar button to see whether they are blocking anything in the page that you need to allow.

Any improvement?
