SuperUser reader giorgio79 wants to know how to find the Chrome extension that is injecting unwanted ads into his browsing experience:
I use Google Chrome and recently noticed random ads showing up, either embedded in web page content or by redirection. When I click on a link, an ad page opens up instead of the proper web page.
I suspect these ads are being injected by a Chrome extension, but how can I find the offending one? The ads seem to appear at random in an intermittent manner.
What is the best way for giorgio79 to find this irritating extension?
SuperUser contributor Oliver Salzburg has the answer for us:
1. Press F12 to open the Developer Tools. Alternatively, you can open the Developer Tools from the Hamburger Menu.
2. On the Sources Tab, select the Content Scripts Tab. You should see a list of all the extensions that load content script.
Content Script is the term used for scripts that are running in the context of the website you are visiting. These scripts have the ability to manipulate web content in any way they want.
3. You can now inspect those scripts and see how they are affecting the web page you are viewing.
Hint: In case they are using minified sources, enable the code beautifier.
