FlashFirebug: A Firefox extension for inspecting SWF files on the fly

Hello, we've just released FlashFirebug 3.4.2 and would love comments and feedback about it. We're also preparing to start development on our next release, so this would be a great time to get feature suggestions and requests.

We'd also love to hear from people who've worked with Flash on the bytecode level as we're looking into advanced debugging features (breakpoints, stack traces, watches, etc). Any technical hints and pointers would be greatly appreciated. Thanks!
