Hi @Kirti_23 

This is the behavior of Firefox, and expectation too; that Target sometimes fails to load in this particular browser. I believe, if you will try in Chrome then it will certainly work.

The reason behind this is some kind of fundamental network error. In many cases, it is caused by a browser plugin (e.g. an ad blocker or privacy protector) blocking the Target request. In today's time, it is generally Firefox's built-in tracking protection called as "Enhanced Tracking Protection". Under this tracking protection, Firefox blocks some network calls. Below is a link that talks more about it.

Now, here is the SOLUTION - You have to disable "Enhanced Tracking Protection" in Firefox, please find below the steps to achieve the same.

• Click on the shield icon in the address bar.

         

• Toggle the switch at the top of the panel from "ON" to "OFF".

         

• Disabling the tracking protection reloads the site page and this time, with Target loaded successfully on it.

Hi
The answer should be focus on CORs policy update
Best practice will be white list all the domain the application/web is using (its good for content security)
