Comment 181 for bug 52667

Thanks, that's a really good breakdown. In my experience Option 2 seems like a good idea, except that it creates tricky consequences. If you base the "sticky" quality off the type of message or other attributes you really have to communicate to the user that "Newsgroup messages will always reply to sender". Otherwise it can appear to people that we're choosing a default almost randomly; you click on one mail message and it's reply all, one news message and it's reply to sender. Also if a person wanted to reply to sender just once and we changed the default after that one time we're likely to confuse them.

Sadly the simplest method of just defaulting to reply all for multiple recipients is going to allow everyone (even the people who would be annoyed by this behavior) to at least always predict what will happen.

For those who want more "sticky" like behavior I believe all that would be necessary is to understand that need and build the buttons with extensions in mind. Extensions would enable people to customize the button type based off the attributes of the message, it probably isn't too difficult right now... well once we have buttons like that at least.
