It seems that LoadInfo's top-level document constructor sets up the wrong top-level anti-tracking principal


(Core :: Privacy: Anti-Tracking, defect, P1)

See this principal. Here innerWindow is the old inner window that the top-level navigation is replacing. It seems wrong to use its principal as the top-level anti-tracking principal.

baku, what do you think?

This is related to It's possible that stopAtOurLevel is mostly false so we always bail our early here, but it could be that the fix to bug 1577298 wasn't completely right...

I tried dropping this write in this try push:

It seems to be fine, but it'd be nice to have a test.

Matt, if you want to work on this, it's great. I can review the code. Let me know.

I'm not really sure where to start for adding a test sorry.

I can upload a patch to just remove the offending call if that's useful!

Dimi, do we still need to fix this issue? Asking because the fission-porting has changed the code a lot lately.

We still use topLevelPrincipal from LoadInfo to get partitionPrincipal at here. But it is only used when we can't partitionKey from CookieJarSetting in some special cases, so in most of the cases, the value of topLevelPrincipal doesn't matter.

I think the right solution now is to find the cases we don't set partitionKey, and then remove TopLevelPrincipal from LoadInfo entirely to prevent using it in the future. Because this value doesn't work in Fission anyway.
