Yeah I was getting this same error in Firefox stable (64bit). I tried stopping the app, clearing cache and data but no fix. I tried the same thing plus restarting my phone, no fix. Tried uninstalling and reinstalling, no fix. Tried updating android, and reinstalling again, no fix. Tried the Beta build, SAME ERROR! Retried restarting one more time for the beta build but still no fix!
