What Permissions Does ProBlocker Request?

ProBlocker requests "Read and change all your data on all websites." This permission is required for any extension that needs to intercept network requests — which is how ad blocking works. ProBlocker uses this permission to block ad and tracker requests. It does not read the content of web pages, form inputs, or passwords.

Does ProBlocker Work with Chrome's Manifest V3?

Yes. ProBlocker was built for Manifest V3 and is available in the Chrome Web Store. It is not affected by Google's MV3 enforcement that removed uBlock Origin and other MV2 extensions.
