Firefox 3.5 - 4.0b1, SeaMonkey 2.0 - 2.0.*, Thunderbird 3.0 - 3.1.*
This update contains a bunch of stability fixes for Venkman, and should markedly improve your debugging experience! Among other things, this update will mean Venkman no longer impacts browser performance unless you start it yourself, and work better with local, Firefox and add-on files.
Firefox 0.9 - 3.0b2, SeaMonkey 2.0a - 2.0a1, Thunderbird 0.9 - 3.0a1
This release has a bunch of bug and stability fixes, once again works with development and beta versions of Firefox 3, and adds some small new features like being able to view profile data immediately, better function name guessing in profiling (no more endless lists of "[anonymous]"!), and should be noticeably faster to start up than previous versions.
