276699 - Chrome should not prefer links

Status: NEW

(Core :: DOM: Navigation, defect)

Description

[[e-mail]]

If you embed <html:a href="http://www.mozilla.org">Mozilla.org</html:a> in
chrome then clicking it will replace the chrome with the Mozilla.org website. I
feel that this is a bad idea and it should instead open in a browser window.
However the way content listeners are chained makes this difficult. I can think
of two possibilities that seem to be able to resolve this issue. In either case
the nsDSURIContentListener needs to return early from IsPreferred if the
docShell is a chrome docShell. Then the code to link doc loaders either needs to
check that the parent doc shell is a content shell before chaining the content
listener, or alternatively copy any explicit parent content listener into the
child doc shell. P.S. Why is nsDSURIContentListener not part of nsDocShell?

What if this were a link to a chrome:// URI?  Would you still want to return
early from IsPreferred?

I guess the problem is that the root URIContentListener just can't tell which
docshell the load is being targeted at, huh?

The question is moot as there is no way you would know.

We plan to change that; the question is what the new interface should look like
and whether addressing this bug should be a design criterion for it.
