A feature from Internet Explorer that I've been missing in Mozilla is nice display of XML files which don't include styling information. This prettyprinting support has been added in recent builds, and I noticed that the nightly build I'm using at the moment has it enabled by default. I was happy to see that it works about as I'd expect. Yay.
There are a lot of fun enhancements in the build I'm using (2002092404) over the 1.2a version I was previously using. My favorite is that you can display the contents of cookies that sites are sending your way as they're being set. I'm not sure why session cookies need to expire in 2038, but you'd be surprised at how many of them have that expiration timestamp.
Mozilla is like the hot rod of browsers for professional dorks.
