Read the publisher’s full description

ニコニコ動画のプレイヤーを2種類の方法(「シアターモード」または「ブラウザ内最大化」)で拡大します。 プレイヤー右下のアイコンでこれらの機能を切り替えられます。 それぞれtキー、bキーでも(ブラウザ内最大化解除はescキーでも)切り替えられます。 ※「ブラウザ内最大化」の利用について(2025年3月11日時点) 2025年3月11日のニコニコ動画更新 ( https://blog.nicovideo.jp/niconews/244917.html ) を以て公式の「ブラウザサイズフルスクリーン」が完全に復活し、この拡張機能の「ブラウザ内最大化」と実質同じになりました。 そして、公式のフルスクリーン機能はモニターサイズかブラウザサイズかによらずfキーで切り替えられます。 参考: 動画ショートカットキー一覧 | ニコニコヘルプ https://qa.nicovideo.jp/faq/show/287?site_domain=default したがって、 【常に同じサイズで拡大する方】 ・拡張機能を使わずに、公式の拡大ボタンかfキーで拡大することをお勧めします。 【両方のサイズを使い分けたい方】 ・公式のサイズ設定を「モニター」にした上でこの拡張機能を適用することをお勧めします。それぞれのサイズ用の拡大ボタンかショートカットキー(モニターはfキー、ブラウザはbキー)で即座に拡大可能になります。 必要に応じてそれぞれの機能をご利用ください。 経緯説明記事 https://blog.dnek.net/entry/2024/08/06/170118 紹介動画シリーズ https://www.nicovideo.jp/user/134113088/series/487379 ソースコード https://github.com/dnek/nicovideo-player-expander X(Twitter) https://x.com/dnek_
