Closed dynamis closed 5 years ago

dynamis commented 5 years ago

Firefox Account や Sync サービスは無効化する

Firefox Screenshots は browser.xul なしでは動かないと思うが、無効化しておく。

dynamis commented 5 years ago

https://github.com/webdino/amethyst/commit/9580374548abc5b07edb0d1294d466c3bb82af8e Firefox Account と Sync サービスを無効化、削除しました。 @dynamis @kou029w

kou029w commented 5 years ago

機能しない about:preferences#sync が残っているようですね

hATrayflood commented 5 years ago

次の最新ビルドでは消えるはずです。

次の最新ビルドでは消えるはずです。

失礼しました about:preferences#sync が残っているのは1つ古いビルドで試しているからでした

kou029w commented 5 years ago

メモ: それぞれの機能を有効化したプロファイルを作成し複製して、新規タブ、設定画面、アドオンなど外部サイトにアクセスせず通信ある結果との比較を調査

kou029w commented 5 years ago

8746d4c5 ビルドにて、about:preferences#sync が消えており、通信が発生しないことを確認しました

確認方法:

  1. Linux (x86_64) PC環境でFirefox 60をインストール
  2. Firefoxを起動、Firefox アカウント、Pocket にログインしたユーザープロファイルを作成
  3. 実機ののrootfsパーティションの /home/root/.mozilla ディレクトリ以下にそのプロファイルをコピーしログを取得
  4. about:blank、about:preferences#syncにアクセスして、外部との通信が発生しないことを確認する

ログを取得する際に実際に使用したコマンド:

# rm -r .mozilla/firefox/myyqvz5n.default/
# cp -a 4s2uzw47.fx60 .mozilla/firefox/myyqvz5n.default
# export NSPR_LOG_MODULES=nsHttp:5,nsSocketTransport:5,nsHostResolver:5
# webviewer about:blank 2>blank.log
^C
# webviewer about:addons 2>addons.log
^C
# webviewer about:preferences 2>preferences.log
^C

アクセスする回数を計測するために使用したコマンド:

grep -E 'Host:[[:space:]]+[^[:space:]]+' /path/to/logfile | wc -l

about:blank
