Is the wifi enabled and connected on the phone? I had a situation once where the hotspot network was relaying data to the connected wifi network on the phone instead of mobile data like you’d expect.

Works fine for me. Have you made sure it’s not caused by an extension?

I have never seen this in all my time using Firefox. It always tells me there’s an update available and prompts a restart but I can still continue using the browser.

So many paths in life that resulted in you not being a dickhead, yet here we are
