You can use AdBlock's resource page to see all the requests a website makes and how AdBlock deals with them. You can also use it to create exceptions, filters that customize what resources AdBlock blocks or hides. A resource is anything a web page asks to download to your browser. It could be an ad, an image, style and formatting instructions, or a piece of website code.


The resource page is available in Chrome, Microsoft Edge, and Firefox. This feature is not available in Safari.


Creating exceptions can be a little bit tricky, and getting it wrong can make a web page stop working. For these reasons, you need to turn on advanced user mode to see AdBlock's resource page.
