You can set a flag on Chrome (chrome://flags/#extension-active-script-permission) to block the extension by default and only activate it when you click the pageAction/browserAction or if you whitelist it (for that website only or for all websites). Also, two extensions come in handy: "Chrome extension source viewer" [1] and "Extensions Update Notifier" [2] (self-descriptive titles). The second one can automatically disable extensions when they're updated. They're honestly a little annoying if you have more than a handful of extensions since they lack some essential features (e.g. viewing a code diff from the previous version), but at least they're open source! :) [1]: https://chrome.google.com/webstore/detail/chrome-extension-source-v/jifpbeccnghkjeaalbbjmodiffmgedin https://chrome.google.com/webstore/detail/chrome-extension-s...
