Comment 5 for bug 222208

I can vouch for the bug. I use basic auth to access RSS feeds for "friends only"
posts at LiveJournal. You can test this using anyone's blog on LJ by providing
the username/password in the url:

http://username:<email address hidden>/~blogowner/data/atom?auth=digest

(make sure to substitute the name of an actual blog for "blogowner")

This is how LiveJournal allows people to check for "friends only" posts by
bloggers. I ran Ethereal during TB's RSS update and it's obvious that TB simply
doesn't pass along the username and password in random cases. Sometimes it
works, sometimes it doesn't. Actually, it wasn't a problem when I only had one
RSS feed with authentication, but I recently change several other LJ feeds to
include my authentication, and now I get the login dialog at least once per update.
