Since russia is a terrorist state I dont really understand why even communicate with them in the first place

This is an unpleasant dilemma. What is the other option? Stick to their principles and let Russia ban Firefox? It’s not ideal but people in Russia can still install add-ons from file.

Agreed - rather give the people there the ability to install this themselves than have them try to block Firefox overall.

The problem is, Mozilla is not doing that. The ability install xpis is censored (oh the irony) in retail Firefox.
