Firefoxフルスクリーンフラッシュが機能しない
Ubuntu Gnome 13.10では、Flashビデオを全画面表示しようとしても、ビデオがフリーズするだけです。フリーズはウィンドウのフォーカスを解除して再フォーカスすることで修正できますが、Flashを全画面表示にすることはできません。ただし、（埋め込みでない）YouTubeビデオを表示すると、フルスクリーンは正常に機能します。
誰も私がこれを修正する方法を教えてもらえますか？ YouTubeが（ほとんど）動作しているように見えるが、それ以外は何もないように見えるのは奇妙に思えます。
あなたがそれらを必要とする場合のために、ここに私の詳細なシステム仕様があります：

助けてくれてありがとう。この問題はしばらくの間私を悩ませており、私はついにそれにうんざりしているので、どの解決策も私がどれほどイライラしているかを考えると良い解決策でしょう。
Mozillaのウェブサイトからこれに対する解決策を見つけました（ https://support.mozilla.org/en-US/kb/flash-video-wont-play-full-screen ）それで十分ですあなたが追加します env LD_PRELOAD=/usr/lib/libGL.so.1ランチャーのfirefoxの前。変更せずに問題を解決しました。
あなたが言ったように、それはアドビのエラーかもしれません、
- ターミナルを開き、
Sudo apt-get update - 次に、ソフトウェアセンターを開き、[更新]（その行に沿ったもの）をクリックしますアップグレード可能なもののリストが表示されます
- スクロールして、「Adobe」、「mozilla」、「media player」、「media runner」、または「fullscreen command」のいずれかを見つけます。
- それらを見つけたら更新してください
- すべて完了したら、コンピューターを再起動します。
- ターミナルを再度開き、
Sudo apt-get update - mozilla Firefoxを実行すれば完了です！
