firefox の shortcut を無効にする

背景

• firefox の shortcut key がうざい
• Ctrl-N, Ctrl-P, Ctrl-m, Ctrl-H とかを無効にしたい

結論

• firefox のアップデート毎に bat (patch) を走らせればよい

手順

1. firefox 更新
2. firefox 停止
3. bat (firemod.bat on windows) を起動
4. firefox 起動
5. Ctrl-N で何も起きないことを確認

内容

Desktop とかに置いておく bat スクリプト

firemod.bat

bash --login -i -c C:/home/app/sh/firemod.sh

起動される shell スクリプト

firemod.sh

#!/bin/bash -x

WORK=/cygdrive/c/home/app/sh
patchfile=${WORK}/_firefox.patch
echo $patchfile

omni='/cygdrive/c/Program Files/Mozilla Firefox/browser/omni.ja'
#SUDO="/usr/bin/cygstart --action=runas"
SUDO="python3 /usr/bin/cygwin-sudo.py"
cd $WORK

if [ -d ../tmp/firefox-omni ]; then
  rm -rf ../tmp/firefox-omni/*
else
  mkdir -p ../tmp/firefox-omni
fi;

cd ../tmp/firefox-omni
unzip -q "$omni" || true

patch chrome/browser/content/browser/browser.xhtml $patchfile
zip -0DXqr ../omni.ja ./*
sleep 2;

$SUDO chmod a+rw "$omni"
$SUDO cp -v "$omni" "$omni.orig"
pwd
sleep 2;

$SUDO cp -vf ../omni.ja "$omni"
sleep 2;

ca=`cygpath ${LOCALAPPDATA}/Mozilla/Firefox/Profiles/*/startupCache`
rm -rf $ca;

sleep 2;
