Web Payments SDK - Firefox minimum version

Hi, what’s the minimum firefox version to run web payment SDK? I’ve some automated tests running with firefox 54 and they started to fail 4 days ago.

Can you provide us some more details? What is specifically failing, and are there any error messages that we can use to help understand the problem.

The payment form is not rendering.

The console error shows:
SyntaxError: expected property name, got ‘…’[Learn More] square.js:1:11870
Use of Mutation Events is deprecated. Use MutationObserver instead. RemoteAddonsParent.jsm:670:4
Error: Square.js failed to load properly

This should have been fixed, are you still seeing this problem?
