It can't operate entirely from within the browser (like It's All Text). I couldn't get it to work. When you press Ctrl-Shift-E (for launching the editor), then nothing happens. If you press it again, you get an error message, saying that the editor has already been launched.

I was right, it was still there, and I was able to successfully install it again (with "dpkg -i firefox_56.0+build6-0ubuntu0.16.04.2_amd64.deb"). And now It's All Text works as expected again.

Otherwise, it might get removed for the newest version, when you upgrade your system. Use "apt-mark showhold" to see that it has worked. You also should save the deb package for future use.

It is not a good idea to use an unsupported browser as their may be
unfixed security holes. An alternative is to install firefox-esr which
will give another six months or so (I believe) of support for the
legacy addons.  You could also consider the Pale Moon browser which is
a fork of FF I believe.
