- Support for private browsing mode,
- Open-in-new-window Firebug now looks like in-browser firebug,
- max version 3.6 since we are not testing on 3.7,
- work around for memory leaks discovered in Firebug 1.5.2
The memory leak fix, console.dir() bug fix and perhaps one more will be merged in to 1.5 for 1.5.3 next week.
