Firefox 3 address bar
 

I've been using the FF3 betas and RCs for a while, and noticed that in the latest RCs, the address bar no longer turns yellow for https: URLs, as it did in earlier Firefoxes and even the earlier FF3 betas. Was this turned off intentionally? I think it was a good feature!

I noticed this as well. I thought that it was just a problem with the development build I was using. If the final version doesn't have this feature, we may have to put a feature request to the developers.
