nsIWebProgressListener should be used instead, or not at all.

16:35         bsmith | keeler: using nsIWebProgressListener works for people
                     | that are listening for web content loads (loads that
                     | occur in docshells)
16:37         bsmith | keeler: But, there are also loads that don't occur in
                     | docshells, like what thunderbird does.
16:37         bsmith | So, you might get some people asking you to explain how
                     | thunderbird should replace its nsISSLErrorListener
                     | implementation
16:38         bsmith | When you create a channel, you pass in some callbacks
16:38         bsmith | and one of the callbacks is a callback that gets called
                     | when the channel is closed
16:38         bsmith | and that callback gets the nsresult for the channel
16:38         bsmith | which you can convert into an NSS error code using the
                     | various PSM functions for doing so
16:39         bsmith | I think nsIDocShell deals with errors that way.
16:39         bsmith | I remember that if you look in Thunderbird's IMAP
                     | implementation, they already handle errors that way
16:39         bsmith | for non-SSL stuff.
16:40         bsmith | So, they basically just need to add more cases to their
                     | switch statement to handle the SSL- and Cert- related
                     | errors

Doesn't look like this depends on bug 846581 anymore. As far as I can tell, there's nothing still using this interface for anything meaningful. (There are some uses in comm-central, but the implementations don't actually do anything.)

ni Jorge in case this needs to be documented for add-on compat. I don't know the timeline for this change but it was announced on dev-platform this week.

Comment 5

[Jorge Villalobos [:jorgev] (he/him)]

A few add-ons seem to use it, but it doesn't look like a big concern. Flagging for future documentation.
