comhome.comdirect.de is a TLS intolerant server that violates the SSL3/TLS "version roll back" rule. The workaround for Netscape 6 is to open the Security Manager, click on Advanced, Options, and disable TLS.
I'm using Mozilla (build 2000102220 as I said above), not Netscape 6. Is PSM only working with Netscape 6? With Security Manager, do you mean that thing I get when I click on the locker icon at the bottom right? I can't change anything there any more, because it is empty now, except for the four tabs and the header. This is strange, because it used to show something, e.g. the type of encryption in use, and I didn't change anything. Okay, that's another bug and I'll file that seperately. I'll try to send an email to comdirect.de, perhaps they can make their server TLS compliant. But still, no response from Mozilla at all is a bit too less in this case, IMHO. It should at least pop up some alert window telling me what you told me, shouldn't it? Perhaps the Security Manager could also tell me what's going wrong. So reopening and changing the summary accordingly.
Dupe of bug 33772 - No warning when connection is not possible. and dupe of bug 52549 - Second PSM window has only the top tabs *** This bug has been marked as a duplicate of 33772 ***
