This is an odd edge case, but if you paste a moz-icon: url with a file:uri into the address bar, it causes a crash in PermissionMessageUtils.cpp[2]. It's just a mozcrash, and it doesn't look dangerous to me (web pages can't load or link to these urls so it would be hard to induce in any case). STR: 1. Load moz-icon:file:///... uri such as [1] in a tab 2. icon from exe with load, then wait a second or so 3. tab will crash after a second or so Reproduces in release (build id: 20181112164519) and nightly 64.0b9 (20181112164519) [1] moz-icon:file:///C:/Users/User/AppData/Local/Programs/Microsoft VS Code/Code.exe?size=16 [2] https://hg.mozilla.org/releases/mozilla-beta/annotate/6226ce7f4038d566fe750b1d13f107146d137463/dom/ipc/PermissionMessageUtils.cpp#l25 This bug was filed from the Socorro interface and is report bp-b10e024d-38cc-40f9-a672-3119b0181116. ============================================================= Top 10 frames of crashing thread: 0 xul.dll IPC::ParamTraits<nsIPrincipal>::Write dom/ipc/PermissionMessageUtils.cpp:25 1 xul.dll mozilla::dom::PContentChild::SendStoreUserInteractionAsPermission ipc/ipdl/PContentChild.cpp:5068 2 xul.dll mozilla::AntiTrackingCommon::StoreUserInteractionFor toolkit/components/antitracking/AntiTrackingCommon.cpp:1312 3 xul.dll nsIDocument::SetUserHasInteracted dom/base/nsDocument.cpp:12896 4 xul.dll mozilla::EventStateManager::PreHandleEvent dom/events/EventStateManager.cpp:512 5 xul.dll nsresult mozilla::PresShell::HandleEventInternal layout/base/PresShell.cpp:7661 6 xul.dll mozilla::PresShell::HandleEventWithTarget layout/base/PresShell.cpp:7480 7 xul.dll mozilla::PointerEventHandler::DispatchPointerFromMouseOrTouch dom/events/PointerEventHandler.cpp:535 8 xul.dll mozilla::PresShell::HandleEvent layout/base/PresShell.cpp:7257 9 xul.dll nsViewManager::DispatchEvent view/nsViewManager.cpp:812 =============================================================

Hmm, so it appears as though there are some principal serialization issues. I'll look into putting a quick fix together. The Thunderbird issue is distinct, they also have some principals which cannot be serialized currently unfortunately. I don't consider their bugs to be part of that issue.
This is needed to use the IPDLParamTraits implementation for nsIURI which is used in part 2 of this patch series.
This should add support for serializing moz-icon:// URIs and other URIs which don't implement nsISerializable, but do implement nsIIPCSerializableURI. This also avoids the continued use of nsISerializable, which is intended for persistance, for IPC, saving unnecessary byte-order swaps etc. Depends on D14434

This is needed to use the IPDLParamTraits implementation for nsIURI which is
used in part 2 of this patch series.

This is needed to maintain full feature parity with the existing
nsIPrincipal serializer while switching to using the PrincipalInfo-based
one.

Depends on D20853

Low crash volume, I guess this can ride the trains.

I'm confused about why the domain doesn't get serialized/deserialized by WritePrincipalInfo/ReadPrincipalInfo. Why add it to PrincipalInfo if it only survives a PrincipalInfoToPrincipal(PrincipalToPrincipalInfo(foo)) round-trip that does not cross processes via IPC? Is it a policy decision because document.domain is dumb?

(In reply to Andrew Sutherland [:asuth] from comment #19)

I'm confused about why the domain doesn't get serialized/deserialized by WritePrincipalInfo/ReadPrincipalInfo. Why add it to PrincipalInfo if it only survives a PrincipalInfoToPrincipal(PrincipalToPrincipalInfo(foo)) round-trip that does not cross processes via IPC? Is it a policy decision because document.domain is dumb?

It does survive when crossing IPC, but it doesn't survive being written to Structured Clone from JS. That's more of a "I meant to get to it but forgot" issue, rather than an intentional issue.

I really want to move document.domain out of the principal object entirely at some point (IMO principal should be immutable & threadsafe), but while it's still in there we should probably preserve it there.
