Firefox Certificate Insanity
Christopher, this kind of insanity and the arrogance with which related feedback is handled, is exactly the reason, why people want alternate browser UI's. Sometimes I really wonder if Mozilla's UI designers serve the users, or if they just serve their ego.
Combine this need for custom UIs with the uglyness of Mozilla's bloated XPCOM APIs and the inability to keep them stable - some people even perceive the situation as sabotage - and you know why developers turn their back to your project.
PS: Colin, you totally forget that FOSS land doesn't only consist of big companies! Expect for big companies nobody, really nobody is paying for certificates. Only alternative seems to be CACert, but their website and the short-livingness of their certificates also make it a pain to use.
