Changes

XULRunner continues to improve on the Mozilla 1.9 codebase. It is possible that Firefox 3 will be [[MDC:XULRunner:Deploying_XULRunner 1.8|built on top of a "private" XULRunner]] (i.e. XULRunner will be installed in the Firefox application directory, and will not be shared with other applications), but Mitchell's [http://weblogs.mozillazine.org/mitchell/archives/2007/05/xul_and_xulrunner_investment.html blog post in May 2007] suggests otherwise.
