Public bug reported:

In Ubuntu Edgy, I fed Firefox an IRC URL, like (Don't click this yet:))
irc:irc.freenode.net/mychannel. A dialog popped up, asking me how I
wanted the url to be handled. I accepted the default, xchat-remote. Then
Firefox started opening _lots and lots_ of tabs. When I tried to close
Firefox, it asked me wether I wanted to close the 376(!) tabs. I only
had one when I entered the IRC URL. I closed Firefox, but then another
Firefox instance appeared and the insanity resumed. I closed that
instance and another appeared, but this time I was quick and closed it
right away. Then it stopped.

My system slowed down significantly. I think this should actually be
considered a security issue, since a script in a web page could open an
irc url, causing a DoS. This is assuming Firefox won't eventually stop
opening new tabs. Even if it does, the user is forced to kill firefox,
loosing whatever they were doing.
