In Tor Browser Alpha 11.5a13 (64bit, Windows 10) I have configured an obfs4 bridge in Settings → Connection and connected successfully to the Tor network. It’s the only configured bridge.
While connected I was surprised that the Browser offers me to remove it:
Is this the intended behavior? Is it intended to remove a bridge while it is actively used?
And in this scenario, there is also the big red button Remove All Bridges
