Edit with Emacs от dakra, stsquad

Allow user to edit web-page textareas with Emacs (and other editors).

Edit with Emacs is an extension for Firefox/Chrome(ium)
that allows you to edit text areas on your browser in a more full
featured editor. It does this in conjunction with an "Edit Server"
which services requests by the browser. This is because extensions
cannot spawn new processes as a security measure.

The extension packages native elisp version that can be run inside
GNU Emacs itself, just follow the instructions from the options page
of the extension. It has been known to work with GNU Emacs and
Aquamacs (MacOS); it is presently not compatible with XEmacs.

Other example edit servers can be found at the project homepage. There
is no reason why other server scripts could not spawn other editors
and currently a number of servers support the simple URL based
protocol.

This extension is licensed under the GPL v3 and development versions
