WARNING: This presentation seems to crash Firefox for me. Had to view it in Chrome. Anyway...
"Disable cache to (re)gain some sanity" because Chrome continues to cache things it shouldn't, including the contents of file:// URLs and in some cases, even content with headers that specify it shouldn't be cached.
mumble grumble
Cool to see some of these features finally documented, though. I had no idea you could drag-drop elements to reorder them.
For those looking to try out the (useful!) Heap Snapshot tool, please be aware that it has a bad habit of crashing tabs. It tends to happen the most when a tab is already using a lot of memory, but sometimes it just happens. So don't do it on a tab that contains any state you might want to hang onto.
One cool feature they don't mention: You can edit code in the script debugger and then hit ctrl+s to update it live in the running page. It's pretty useful for experimenting or for adding tracing points to existing code.
Kevin, thanks for mentioning the Firefox crash. I opened a bug report to track the issue: https://bugzil.la/798244
I bisected the recent Nightly builds and I believe this crash was a regression in Nightly 18.0a1 (2012-09-29). I was not, however, able to reproduce this crash on Aurora 17.0a2 builds. What OS are you running? (I'm running Mac OS X 10.8.)
