Firefox will not work without WiFi on Metropcs 4g lte network
I can use Firefox on WiFi but if I am using the 4G network I just get a message that I must sign up for the MetroPCS Hotspot plan. That makes no sense. I'm not trying to tether with my phone. I can use the built in browser and Chrome but, Firefox is a complete fail without staying on WiFi at all times.

This likely depends on Firefox's user agent.
If you have installed the desktop by default extension you should uninstall that, https://addons.mozilla.org/en-US/android/addon/desktop-by-default/
If you don't have that extension install then would you install the Phony extension and try the various user agents listed? We suspect that MetroPCS is lumping Firefox for Android with desktop Firefox. Setting the user agent to one of the Chrome values or iOS values should allow Firefox to use the MetroPCS network. Please let us know if that works around the issue.

Unfortunately if MetroPCS is blocking all Firefox user agents this is something that MetroPCS will need to fix. We can try to contact them but feedback from their customers can be more effective.
