We were discussing earlier today on Vidyo, but just confirming that we 💯 want to modify ftp: and file: protocols.

@pdehaan , do you mean remove them from the list? Can you elaborate?

[pdehaan]

@biancadanforth Basically I was just looking for confirmation that we wanted to modify files from ftp:// and file:// protocols and limit this to just /https?/.

[gregglind]

File yes. That's how we do local testing.
Ftp: I have no idea of how users can / would even open ftp links! I think it's safe enough, but if we want to remove it, I have no objection.
