It complains about not having 'object-src' set to 'self'. This header works fine in Chrome, Edge, Firefox ... Is it something that will be fixed or is it the intended behavior ? thanks. 1742396 1 ap 2021-03-22 12:50:56 -0700 This seems unlikely to be intended if it's different from other browsers. Probably an artifact of having PDF loading implemented using plugin code paths. 1742442 2 thorton 2021-03-22 13:35:46 -0700 Kate, is this related to https://trac.webkit.org/changeset/271650/webkit? 1742443 3 thorton 2021-03-22 13:35:54 -0700 (or maybe a dupe of it?) 1742467 4 alexandre.robuchon 2021-03-22 14:16:19 -0700 It looks related indeed. Sorry I didn't find the ticket. Is the patch in 14.0.3 or do I need to get the nightly to test this ? 1742896 5 katherine_cheney 2021-03-23 10:27:28 -0700 (In reply to alexandre robuchon from comment #4) > It looks related indeed.

You should be able to test it using the latest Safari Technology Preview (https://developer.apple.com/safari/technology-preview/). 1742930 6 alexandre.robuchon 2021-03-23 11:54:40 -0700 It works like a charm. No plugin error. 1742931 7 alexandre.robuchon 2021-03-23 11:57:23 -0700 *** This bug has been marked as a duplicate of bug 220665 ***
