main app/Applications/Google Chrome.app
cache files~/Library/Caches/chrome_crashpad_handler
app prefs~/Library/Preferences/com.google.Chrome.plist
main profile~/Library/Application Support/Google Chrome

Mozilla Thunderbird

main app/Applications/Thunderbird.app
(download from https://www.thunderbird.net/en-US/thunderbird/all/)

main profile~/Library/Thunderbird
