port in works

Offers a lot of features that don't exist in other translation
extensions. Offers Wiktionary definition, pronunciation
key, Google Translate and pronunciation in English and
another language of choice. Which makes it possible to
use it as an English-English dictionary AND foreign
language-English dictionary at the same time.
No response from developer on e10 even, so it's unclear
if this is still worked on.

Quick Dictionary

Mostly

Mostly UI and ease-of-use difference,
with small differences in functionality.
Supports bilingual dictionary and
Google Translate, but no side-byside definitions. Cannot set up to
open by simply selecting the text.
Extention works in a new window
rather than a simple pop-up. Seems
not to work on some websites and
text fields.

Instant Translate:
Ultimate Translator

Limited

Only translation. No Wiktionary. No
pronunciation key. No dual-language
translation. No English monolingual
dictionary.

Feature Parity
[1]
WE notes

[1] Full - replicates all features of original add on; serves as a direct drop-in replacement for everyone
Mostly - replicates all main features and most minor features of original add on; serves as a good alternative to the original for the vast majority of users
Partial - replicates most main features, but can be awkward to use and/or is missing a lot of conveniences; may be an acceptable alternative for some users
Limited - only replicates some main features, and can replace the original add-on only in combination with other add-ons & modifications; not an acceptable
alternative for many users
[2] Flash cookies are stored in:
%APPDATA%\Macromedia\Flash Player\#SharedObjects
[3] one click toggling of Java, Flash, Silverlight, Javascript, WebGL, WebRTC, cookies, images, animated images, and CSS
[4] Hide bookmark labels:
.bookmark-item > .toolbarbutton-text {
display: none !important;
}
[5] would like to see an example of a .css code that replicates removing the navigation bar and having it reappear on hover. Especially the stylized
navigation bar option.
[6] .tabbrowser-tab {min-width: 16px !important;}
.tabbrowser-tab {clip-width: 16px !important;}
[7] #alltabs-button {
visibility: visible !important;
}
[8] @-moz-document url(about:privatebrowsing) {
html {
display: none !important;
}
}
[9] Shows full image when you hover over a thumbnail.
[10] Adds an additional quit dialog that will appear when Firefox would not normally prompt.

[11] <-- Any thoughts on how to find context menu entries in a FF57+ world? (Or more specifically when "Menu Wizard" won't run any more?) (Could keep
a pre-57 instance just for this, but see problems with that as well)
From Firefox's source code:
https://dxr.mozilla.org/mozilla-central/source/browser/base/content/browser.xul#315
https://dxr.mozilla.org/mozilla-central/source/browser/base/content/browser-context.inc
You can search "menuitem id=" (in quotes) to find others.
Also see:
https://github.com/Timvde/UserChrome-Tweaks/tree/master/context-menu
<-- Thanks! I guess for extensions it is a matter of cracking open the stored XPI and doing something similar.
