We are calling APIs from other domain, the API result is json which has contents for our site. ex: our site is on https://www.abc.com/mysite and it is calling APIs from other domain, https://www.otherdomain.com/api/jsondata.
But this is working fine in all browsers except Firefox in which tracking protection enabled default or users set tracking protection enabled. All API calls are blocked that made our site empty without any content loaded. The error in browser console is “The resource at “https://www.otherdomain.com/api/jsondata” was blocked because tracking protection is enabled”.
It is noted that for the users using the latest Firefox 63.0 , the content/images are not loading in our site. This issue occurs because the Tracking Protection feature (not popup blocking) is enabled on the newest Firefox version: Firefox Quantum 63.0.
