Both the site's server certificate and my client certificate were issued by a private CA. The CA certificate is installed in Firefox. Works pretty well. But now there is a web page with an RSS newsfeed (Mediawiki) in the protected area of the webserver. Since I have subscribed to this RSS feed, firefox does not select the client certificate anymore, when accessing the server. As soon as I removed the RSS bookmarks, everything worked well again. I guess that Firefox accesses the RSS feeds at startup. Since this particular RSS feed is accessible only with a client certificate or a one-time-password, the RSS access fails at startup. This failure seems to drive firefox in a state where it can't use the client certificate anymore. Reproducible: Always

Hadmut: Are you still seeing this issue in Firefox 3.5 or 3.6?

Moving this bug to the RSS component.

No reply, INCOMPLETE. Please retest with Firefox 4 or later and a new profile (http://support.mozilla.com/kb/Managing+profiles). If you continue to see this issue with the newest firefox and a new profile, then please comment on this bug.
