Brave Browser: Azure Portal - Something Went Wrong
TL;DR - In the last few days (start of 2021), the “Shields Up” feature in the Brave web browser seems to be flagging a JSON file as a cross-site tracker when creating a resource in Azure, causing the blade to not load. To work around this, you can go “shields down” for portal.azure.com.
I logged on to my machine yesterday, same as any other day, and went to start deploying some resources to Azure via the Azure Portal for a customer, nothing out of the ordinary.
