Summary: Lack of webRequestBlocking API or ability to remove X-Frame-Options
Product: WebKit Reporter: Carlos J. <carlosj-webkit-bugzilla>
Component: WebKit ExtensionsAssignee: Nobody <webkit-unassigned>

Hardware: Unspecified   
OS: Unspecified   

Description Carlos J. 2022-10-17 04:43:49 PDT 
The webRequestBlocking is not supported in Safari. One of the use cases in extensions is the ability to remove the x-frame-options header from requests so some pages can be iframed within the extension popup.

Thank you for the report. This will continue to be tracked by Apple internally as a safari issue, not a WebKit one.

We are tracking bugs in Bugzilla for Web Extensions now as we move extensions support from Safari to WebKit.
