Hang in writeBytes() with Firefox 85
I tested my patches for tor-browser-build#40168 (closed) and it turns out that Tor Browser is not starting up. It's just sitting at:
Jan 03 17:26:20.000 [notice] Bootstrapped 0% (starting): Starting Jan 03 17:26:20.000 [notice] Starting with guard context "default" Jan 03 17:26:20.000 [notice] Delaying directory fetches: DisableNetwork is set.
After some back and forth it turns out that it is hanging in
aConn.binOutStream.writeBytes(cmd, cmd.length); in
