I'm seeing the same in Epiphany linked against xulrunner 1.9.

According to http://www.ietf.org/rfc/rfc2396.txt Appendix D, the href attribute "must be an absolute URI", but also states that "This appendix does not form a part of the URI specification and should not be considered as anything more than a descriptive example."

The error message is really weird though, and in any case this is a (serious) regression since it breaks perfectly valid websites.

The HTML 4 recommendation which is more authorative on this matter than RFC 2396, states that the href attribute "specifies an absolute URI that acts as the base URI for resolving relative URIs".

See http://www.w3.org/TR/html4/struct/links.html#h-12.4 for more details.

We were wondering if this is still an issue for you. Can you try with the latest firefox version? Thanks in advance.

First thing I see is that they have changed the URL (and left a zillion broken links in their trail... fantastic!)

The new URL is now: http://1427.bridge.no/modalsmesterskap08.xhtml

I don't have a Linux computer available at the momemt, but I've tried with firefox 3.0.5 on Windows Vista and that works fine.

I can no longer reproduce this problem with my test cases that previously triggered this bug. Both absolute and relative urls in <base href="..." /> result in a rendered page, i.e. no parsing errors anymore.

For completeness, the issue was not the <style> tag, but a non-absolute url value in the href attribute on the <base> tag, which is officially not allowed, but yet is sometimes used and hence should just do The Right Thing.

Thank you, Vidar and Wouter, for your quick reply. Thus I am closing this bug.
