Looks like the site started checking and enforcing user agents. Seems as there is no functionality problem as spoofing it, has everything start working.

On the latest version of Firefox.

Trying to attach a screen capture but it errors on upload ☹

This is blocking any site interaction as it removed the top banner, and reply button.

The forum is hosted with Discourse, I suspect they just need to update to support the latest version of Firefox
