Is Google Analytics Debugger safe?

Clean risk

Google Analytics Debugger redirects Analytics script requests and adds a GTM debug cookie when the user turns debug mode on.

When the user enables debug mode from the toolbar, the extension reloads the active tab and intercepts Google Analytics, DoubleClick, and Google Tag Manager script requests. It redirects Analytics requests to Google's debug script URLs or appends a debug parameter, and it adds or replaces the GTM request Cookie header with gtm_debug=LOG=x.
