Not a new Feature for Windows, to use an enterprise CA to create server certificates. And Firefox added the possibility to trust those certificates ages ago – but still you’ll get an TLS-error-message (in German „Kein Verbindungsversuch unternommen: Mögliches Sicherheitsproblem“). This is no Security-Problem, it’s just a problem of using stupid defaults causing people to waste their time and providing no little level of security, since a CA operated on my own is much more trustworthy than public CAs which firefox trusts blindly. Solution Open about:config and changeRead More →

The Firefox-Developers know best what’s good for their users, so they hide a bunch of Settings in about:config so it’s hard to find them.

I just gave someone the advice without being asked (ignoring all i know about „nonviolent communication“ – sorry for that!) to include a „Scope“ in his blog: he wrote an article how to setup a Raspberry-Pi but skipped all security considerations about how to setup a productive computer system. I assume many readers of his blog don’t have a clue how to harden a linux-operated Raspberry-Pi.
