Please, include a guide of how to get to the preferences site on Firefox. It is not the same as the Github guide, and I had no idea where to go

テクノロジーブログをよく読みます。単語がすぐ判ります。localのPDFの単語も判ります。マニュアルを読むときに便利です。

Super excellent dictionary, thank you. For those having some trouble getting the english-english dictionary to work: here's some more info for mouse dictionary for firefox:
follow all the links, all the information is there.

info for the english-english dictionary is at the bottom of the page.

Download the whole lot, i.e. the zip file
Unzip on your hard drive.
To import the dictionary data, choose the following options:

Character set of dictionary data: UTF-8
Format of dictionary data: JSON
Choose file: dictionary.json

Plus, in the browser extensions navigate to: Manage Extension Shortcuts
to select what keys to activte the plugin, (ALT+Z is suggested)
the shortcut activates it and de-activates it too. Good luck, it's worth the work :)

if this add on is useful... its not very intuitive. spent about 10 mins trying to figure out how it works... to no avail.

非常に便利で毎日のように使っています
Firefox版の更新もよろしくお願いします

sooo cool

Perfect for my purpose. Very quick and efficient.

The browser add-on for translating web pages does not work on addons.mozilla.org. What exactly does your add-on do? I don't understand hieroglyphs.

英単語にマウスポインタを当てると訳語が表示されます。さらに素晴らしいことに辞書の待ち時間がほぼありません。

スクロール機能を持つマウスやタッチパッドをお使いなら、片手の操作のみで辞書を引きながら英語のサイトを全て読むことができます。

非常に便利ですが、Firefox版のほうもアップデートをお願いしたいです。
Chrome版は頻繁に更新してるようですが、こちらはもう1年以上更新がないようで。
