Figure out what happens when a user's chosen transport is removed from bridge_prefs.js in an update
I am planning to deactivate meek-amazon. I planned to first simply remove it as an option in Tor Browser by removing the meek-amazon line from bridge_prefs.js. That leaves the question of what happens when someone is using meek-amazon, and then they upgrade to a newer Tor Browser that doesn't have meek-amazon in bridge_prefs.js?
If it continues using a cached meek-amazon bridge line, that's great; that's the best outcome. We'll keep the bridge running for a while.
If it crashes or falls back to no pluggable transport, then we'll have to think about it.
Does anyone know offhand what will happen?
