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.

excelent idea, it would be better if is used with a shorcut key that opens the emacs buffer.

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!

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!
