Relatively simple to install and use in Emacs, (of course on Firefox side it's a click or two.)

I can also confirm that it works fine with Emacs-mac on Macos (for at least the last several years of emacs versions).

Works great. I just had to install `edit-server' with `M-x package-install edit-server RET' and add
(require 'edit-server)
(edit-server-start)
to my init file.

This is a life saver and can replace the no longer working It'ts All text extension (under condition that you know how to use the Emacs editor).

I use it for example to edit "technical" Mediawiki pages.

I was a happy user of It's all Text, which stopped working with Firefox 57+. When searching for a replacement, I found Textern, but it was cumbersome with this third-party python edit server (but editor agnostic, for sure). For Emacs users, the edit server is a package on MELPA, so installation is straightforward. The counterpart is that it's Emacs-specific.

I can now happily edit text areas with my editor of choice again.

Beautiful. Spreading the Emacs power and love everywhere. The Lisp Machine lives on haha!

It works very well, good job.

Suggest put the following documention in the readme for easy to use:

1, Install edit-server in emacs

It's in "Settings->Information"

2, Start editing in firefox with shortcut key "Alt+Enter" when focused on textarea

It's in "Settings->configuration", please enable "Alt+Enter" by default.

3, The actions support by edit buffer

`C-c C-c` to done edit

I love emacs and I've been looking for this kind plug-ins for firefox!
It's very helpful when I edit web based BTS. Thanks a lot!

I love this add-on. It does exactly what I want. Thank you so much!

I'm very glad for this extension, and it works well. Good work! However, there is one issue: on certain sites, the text boxes have buttons in the lower-right corner where this add-on puts its own "Edit" button. In some cases, this is a "Post Message" button, and when I try to click on "Edit", my message gets prematurely posted.

It would be helpful if one of the options for this add-on would be for us to override the default location of the edit button within text boxes.

I know that I can still edit using the button in the toolbar, but it still would be desirable to be able to specify a different default edit-button location for text boxes.

It would also be desirable for this add-on to optionally launch emacs with a specific environment variable or command-line option, if it doesn't recognize any existing emacs sessions with `edit-server` running. I could write emacs startup code to recognize this environment variable or command-line option and if it appears, to then launch `edit-server` within my startup code, so that it could be used within this app.

But again, good add-on, and good work!
