@JaredBusch Yes, I read it, and it appeared to me to be the same issue you described. Don't shoot the messenger just because you didn't like the chosen solution. 🙄 :face_with_raised_eyebrow: :face_with_stuck-out_tongue_winking_eye:
I installed Firefox Portable and removed standard FireFox. Something between v32 and v42 changed the way that profiles are handled and they can't deal with data that's copied/imaged in the way that Personas/View handles %appdata%.
Odd. I haven't run into this yet, I'd knock on wood, but it's all fake plastic around me right now.
