uMatrix is a browser extension that lets you control what kind of content gets loaded on your site, from block scripts and ads to iframes and media.

If you want to allow all kinds of requests, you can turn off the controls completely.

If you want to allow requests from a certain site or browser, you can control which ones are allowed and which ones are not.

If you want to allow a class of requests, you can do it by clicking on a list of the requests and allowing each one individually.

uMatrix is not an ad-blocker. It's a browser extension that lets you control the requests your browser makes to the website you're on. It doesn't stop ads. It just lets you decide whether you want to see them or not.
