Description of the issue:
Brave shield blocks Figma font helper.
I installed the Figma macOS font helper tool (https://www.figma.com/downloads/) and I had to deactivate the Brave Shield in order for it to work. Apparently, the shield blocks the HTTP://127 requests.
Problem appears on:
figma.com (whatever Figma file you open after logging in)
Brave v 1.21.74
