this jquery injection looks kind of dangerous. Looks like code from code.jquery.com is loaded into any page. Say I go to https://secretsquirrel.com and they have been very careful to only load javascript from their own domain but now it can also load malicious javascript from https://code.jquery.com.
it also disable CSP. i'm not exactly sure how the extension works. maybe it is turned on/off on per tab basis and defaults to off which would be quite safe. but if it defaults to on then it can be kind of risky.
jquery is injected carefully by artoo so it does not break anything on the host page. However, CSP override is not default on artoo and you have to install the chrome extension to perform this. But this extension has solely to be activated when scraping and only developers should use them while knowing its effects.
