JSON pretty-printer for Firefox: JSONovich :: Add-ons for Firefox
A few months ago I released a script to install a 32-bit Adobe Flash plugin to a 64-bit Firefox, but it doesn’t seem to work in Gutsy beta. Here’s an updated one. I upgraded my laptop to Gutsy and used this one to get Flash working.
Edit: I did a complete reinstall later and learned that Gutsy knows how to set this up by itself. So there’s no need for this script anymore. And that is a very positive thing!
