Creative Audigy 2 ZS design flaws

I would really like to know what the designers at Creative Labs have in mind when they design sound cards. Their cards seem to be broken by design. The Live card was bad enough with its random collection of DACs and DPS's, but the Audigy 2 ZS seems no better. Aside from the fact that it's advertised as 96 kHz and 24 bit, which it isn't, it has serious design issues. I had some sound anomalies, so I decided to measure and test. I found: Read More »

Disabling http(s) trimming from Firefox address bar

Some time ago, the Firefox developers decided it was a good idea to trim the http(s):// from the address in the address bar. Since then, I've been getting HTTPS site where I don't want it, because I can't see what I'm doing.
