Bugzilla

As stated in Comment 4, this is caused by Firefox blocking ebay-owned subresources on ebay properties. The entity list should prevent that from happening, so it sounds like there's an issue with Firefox loading the entity list. 

Unfortunately I can't reproduce on a fresh Firefox 80.0.1 profile on Linux (`20200831163820`). I can force the issue to reproduce by disabling the entitylist, i.e., by clearing `urlclassifier.features.socialtracking.whitelistTables` and `urlclassifier.trackingWhitelistTable` and restarting the browser.

Can I ask one of the folks that is able to reproduce to do the following:

1. Go to `about:url-classifier`.
2. Change "List type" to Entitylist
3. Search for `https://ebay.com/?resource=ebaystatic.com` and `https://ebay.com/?resource=ebayimg.com`.
4. Share what is output under "Results"

Also please try clicking "Trigger Update" next to the "mozilla" provider in the providers table. Does "Last update status" say success after you do so? If not, is there an error? (If successful, please try ebay.com again).

Lastly, please go to `about:config` and let us know what you have `urlclassifier.features.socialtracking.whitelistTables` and `urlclassifier.trackingWhitelistTable` set to.
