Mozex.
September 20, 2006, 05:13 pmI just installed mozex on my box at work. It's a Firefox plugin that allows you to use external programs to "edit content of textareas; view page source; handle mailto, news, telnet, and FTP links; download files". I'm using it to edit textareas and view page source with vim!
Just use /usr/bin/gnome-terminal -e "/usr/bin/vim -e %t" in your mozex configuration (initially, I didn't have the quotation marks and it caused a problem for gnome-terminal).
In case anyone was wondering, I love vim. I've been using vi-based editors for over ten years and I'm still learning new tricks in vim.
