UIFlow stopped working on a Firefox Browser (Linux)

Today, after calling the [https://flow.m5stack.com/](link url) URL at the Firefox Browser
I got a blank screen after 4 seconds load time. At the debug section I see an error as printed below. The Google Chrome browser is working OK with this URL. Thanks for checking:

SyntaxError: invalid regexp group
