@dstiltes, these improvements are probably fairly lightweight. One is just syntax highlighting, one seems to catch up with Chrome(ium), and the last is just lightweight editing of properties.
They are also not making their own life easier, as they are browser developers, not web developers.... it is important for platforms to keep developers happy - to quote Steve Ballmer "developers, developers, developers, developers, developers, developers, developers...." (the video is easy to find, as is the rather better dance one)
@tedster, I think it just means that add-ons are assumed to be compatible unless declared incompatible with the new version, whereas previously add-ons were assumed to be incompatible unless declared compatible. It makes sense as most add-ons will work fine with new versions of Firefox, so waiting for an upgrade to all of them before they would work with a new versions was unnecessary - but it will mean more bugs in add-ons because some are sure to break. It works for Chrome....
