As far as I read the source of the extension it&#x27;s still per tab, not dependent on the origin of the script but just the URL of the whole tab and then it&#x27;s all or nothing, completely different from Old Opera&#x27;s behavior?<p>&gt; <a href="https:&#x2F;&#x2F;github.com&#x2F;maximelebreton&#x2F;quick-javascript-switcher&#x2F;blob&#x2F;master&#x2F;src&#x2F;js&#x2F;core.js" rel="nofollow">https:&#x2F;&#x2F;github.com&#x2F;maximelebreton&#x2F;quick-javascript-switcher&#x2F;...</a><p>That is, if the url of the tab is whitelisted, the code from all sites is run in the given tab with this extension? Opera worked differently.
