This happens while logging in to school's content management system at effie.itcollege.ee. This only happens with Firefox included in Ubuntu 9.10 release
I encountered this error (the certificate warning page not being displayed because of an XHTML parse error) in Firefox 3.6.9 on Ubuntu 10.04.1 LTS. Upgrading to Firefox 3.6.10 appears to fix the problem.
I should note that this occurred when Firefox had been updated to 3.6.10 by the package manager, but I had not yet restarted Firefox to get the new version. Compare this Ubuntu report: https://bugs.launchpad.net/ubuntu/+source/firefox/+bug/555489 By the way, bug 575856 sounds rather similar.
I haven't seen this issue in any of the current Firefox versions. Can you still reproduce it?
