This extension is crucial, & everyone would use it, if only it had a graphical icon in the toolbar.

That's Disappointing...too bad...

新しくなったFirefoxで複数のタブを一気に消すのにアクションが増え面倒くさくなった。このアドオンもデフォルトだと3キー（shift+ctrl＋F1 or F2）の同時推しなのでちょっと面倒。これを2キーで出きる設定にしたので使いやすくなった。

（キー変更方法）
ツール → アドオンとテーマ → 『拡張機能の管理』の右上の歯車『⚙』 → 拡張機能のショートカットキーの管理

私はctrl＋F1（左側全閉じ）、ctrl＋F2（右側全閉じ)にしました。

Alt+w conflicts with the "whole word" search in the search panel, setting it's value when I not expect it - would really love to have the shortcut configurable or to be assigned to something different.

This extension makes web surfing much more comfortable for me. But there is only one issue which is a little bit annoying: if the Firefox find bar is open then the keyboard shortcut ALT+W is occupied by toggling the find option 'Whole Words" instead of closing other tabs. Thus it would be useful if there was an alternative keyboard shortcut for "Close Other" (e.g. Alt+Shift+F3) or even better if the keyboard shortcuts were configurable

Thank you developed this function for us, but I want to request you to develop how a function allows us to change other keyboard shortcuts, because I want to control the shortcut by one hand.
