Summary Extension frames fail to be embedded on websites

Trying to put a view (html page) from a web extension into an iframe on a website. The html file is listed correctly in web_accessible_resources, however when I'm trying to load it, I get the following error: Failed to load resource: The operation couldn’t be completed. (Cocoa error -1008.) Sample extension can be found here: https://github.com/carlosjeurissen/webext-tech-demo-extensions/tree/main/issues/safari-8986072-frame-extension-on-website In browsers like Firefox and Chrome. The frame is loaded and says "frame". In Safari it doesn't load and thus is blank.

Thank you for the report! This will continue to be tracked as a Safari issue, not a WebKit one. rdar://73826149

@alexey proskuryakov is there a clear line between what regards an issue as being a WebKit or a Safari issue? What is the scope of "WebKit Extensions" on bugs.webkit.org, and what issues should be reported elsewhere? Considering there is no browser UI present in this issue.

The vast majority of extensions functionality is in Safari, not in WebKit. There is an occasional need to add or fix supporting code in WebKit. Tim will correct me if I'm wrong, but I'm guessing that this component is mostly for those issues filed by development team, not as much for reports.

Tim tells me that it's fine to track these as open bugs in Bugzilla, in general.

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

Just tested in Safari Technology Preview 192 and the issue is still there.

This can be reproduced on Safari Version 18.3.1 on macOS 15.3.2.
