Comment 49 for bug 68040

For those using a Mac running 10.3.x or 10.4.x, Safari 2.0.1 now supports
showModalDialog(). This has been my ONLY reason to hold onto IE.

My understanding (although rudimentary) is that Safari's JavaScriptCore is a
framework for Mac OS X that takes the cross-platform KJS library (part of the
KDE project), combines it with the PCRE regular expression library, and makes it
work with Mac OS X technologies. May be a way to facilitate adding this to FF.

Again, sorry if this is a dumb thought.
