I guess it may be due to Adblock Plus. I disabled ABP once and they were working fine..after displaying all the ads.

Based on the fact that I cannot reproduce the issue on the latest Firefox release (51.0.1) or on the latest Nightly (54.0a1) with Adblock Plus enabled and comment 3, I will mark this issue as Resolved-Worksforme.

If anyone can still reproduce the issue on the latest Firefox versions, feel free to reopen and provide more information.
