Firefox: Error: Method setWidgetProps not found: unexpected nullish value: undefined

On Firefox, some components are stuck on skeleton loading and report as finished rendering even though they don’t, it happens on already published apps too, such as Booking.com

Do you happen to have a minimal reproduction? Are you sure it’s isolated to Firefox?

Hey, thank you for the reply.

I tested it a bit more, it happened to me on any app I span up, including published ones. At chrome everything worked. I had an idea and disabled my firefox extensions, it seems to work now. I wanted to report on what extension caused the issue so I tried to pinpoint it, but it seems like it works now regardless of extensions (even if I enable them all), so it was probably some weird state in the browser itself.

Thanks
