Olifante posted instructions for setting up TextMate to edit TextArea’s in Firefox using the recently updated Mozex Extension.
This is a huge improvement. I was already doing the same thing much of the time by copying and pasting. I heard about the extension and thought about what it would take to get it working well with the latest versions of Firefox and everything myself, but was glad to see that I don’t have to – the author made the necessary improvements. Great work, Vladimir Marek!
With extensions like these, Firefox beats Safari and Camino by leaps and bounds (It’s the Ecosystem, Stupid!).
