塩濱健 (ID: 0000004050d5686a) Voted 5 ★ - Updated 10/06/2023 Webの制作では長年利用しており、お仕事には欠かせないアドオンの1つとなってます。 近年、銀行やさまざまなサービスのログインエラーなどにこの拡張機能が影響していることがわかり、設定を見直しました。 拡張機能を右クリックし、メニュー内の「サイトデータの読み取りと変更」の設定から「拡張機能をクリックした時」に設定変更して、自動読み取りをしないようにすることで、自分の場合は解決できましたので、もしお困りの方がいたら、設定を変更することで回避可能かもしれませんので、お試しください。

Izumi Sasaki (ID: 000000e6adc64234) Voted 4 ★ - Updated 01/10/2022 機能としてはバッチリで助かってます。 ブラウザの右上に小さく表示されるのでエラーに気づかないという問題があります。 指定した自分のサイトだけエラーチェックするように設定しているので、できればもっとエラーがわかりやすいようにしてほしいです。

さむ (ID: 000000e5e20f9be3) Voted 5 ★ - Updated 01/11/2020 HTMLを参考書のとおり入力しても、どうしても、トップページのタイトルの日本語が文字化けしてししまっていました。HTMLの記述を散々探しても違いが見つかりませんでした。この機能を使ってファイルを見比べたところ、テキストエディタ―で入力しているタイトル部分の日本語自体が文字化けしているのが分かりました。文字化け箇所を正しく日本語に直すと、見事にトップページのタイトルが正しく表示されました。
