Chrome now includes a “Script Bubble” feature that shows you how many scripts are running on a specific page and which ones. The feature could potentially allow users to spot a malicious extension more easily.
There’s no way to stop the extension from running on the page through the Script Bubble, which is something I’d really like to see. Further, I’d like to see scripts on on pages on a whitelist as well and options similar to the other content settings.
You can enable the feature under chrome://flags.
