The NPAPI reference suggests that we should return false, at least in some cases: http://developer.mozilla.org/en/docs/Gecko_Plugin_API_Reference Some compatibility testing will be required, because the NPAPI documentation isn't very specific. 86508 1 ddkilzer 2008-07-20 15:25:54 -0700 Related to Bug 18234? 86519 2 zwarich 2008-07-20 20:32:02 -0700 (In reply to comment #1) > Related to Bug 18234? Yes, that bug should probably depend on this one, or maybe even be marked a duplicate. There is now no real support for NPN_SetException. 1876811 3 ahmad.saleem792 2022-06-20 10:42:34 -0700 From Webkit Github mirror, I am only able to find following references about NPN_SetException: https://github.com/WebKit/WebKit/blob/25eed588cb7fcdb340b0783e2c2c7022cd48897a/Source/WebCore/bridge/testbindings.cpp#L148 I think all other references of it are removed as part of NPAPI removal, since it is not supported from Safari 14 onward and also not supported on WebkitGTK port. I think any further enhancement to NPAPI is not in radar and this can be marked as "RESOLVED WONTFIX". Thanks! 1876812 4 webkit-bug-importer 2022-06-20 10:43:02 -0700 <rdar://problem/95544910>
