Ionic serve --lab "Content Encoding Error" in Firefox

I recently began receiving a “Content Encoding Error” when running ionic serve --lab. Not sure exactly what I did to my project to cause this, but before I comb every line of code to find the culprit, has anyone had this happen? Any obvious solutions I might be missing? The only things I can think of off the top of my head that I changed were adding Ionic Push.

This was an error in my ionic.project file, which is interesting - when I installed Ionic Analytics a new proxy entry was added and it caused ionic serve to break. Took out the proxy setting and now we’re good, but now I have to comment out analytics when testing locally. Which I suppose isn’t a big deal, but still kinda wierd.
