Linux上のブラウザでのプロキシの設定方法



●Braveブラウザ

　参考URL：Configure Proxy for Chromium and Google Chrome From Command Line on Linux

　Linuxのシステムの設定でプロキシを設定済みであっても、プロキシを使用しない（ダイレクト）形で接続していまいます。
　ターミナルで下記のように実行します。 
$ brave-browser-stable --proxy-server="http://proxy-ip:proxy-port" &

# エラーを出力させたくない場合
$ brave-browser-stable --proxy-server="http://proxy-ip:proxy-port" > /dev/null 2>&1 &
　ターミナル上にエラーが出力されますが、問題なく利用できます。
