Advanced Content Permissions
-
For things like iframes, sockets, javascript, css, XHR; it would be nice to get more fine-grained permissions. So that, for example one could:
- Allow only 1st party javascript on the domain, block 3rd party
- Allow certain 3rd party scripts to be loaded on certain websites
- Whitelist certain CDNs to always allow scripts to be loaded from them
- Prevent XHR requests to other domains
Effectively, functionality similar to advanced mode "uBlock Origin" and other such extensions
