822085 - "Assertion failure: failedURI (We don't have a URI for history APIs.)" with onunload navigation to error page

Status: RESOLVED INCOMPLETE

(Core :: DOM: Navigation, defect)

Description

[Jesse Ruderman]

Assertion failure: failedURI (We don't have a URI for history APIs.), at docshell/base/nsDocShell.cpp:7817

Opposite of bug 750145?

Bug 820200 has the same assertion message, but otherwise seems unrelated.

Bug 750145 was about subframe loading. This bug seems independent.

The main problem here is "unload" handler clears nsDocshell::mFailedURI, which must not be null during trying to display an error page. A little more serious problem is probably URILoader called DoContent() (and CreateContentViewer()) after |window.close()| would have been called.

Hi Jesse!
With the attached test case, I was not able to reproduce this issue on Firefox Release version 85.0, and ESR version 78.7.0 on Windows 10.
Because firefox has changed quite a bit, we would like to close it.
Could you tell us if the same problem still happens?

Hi,
I'm marking this as Resolved-Incomplete due to lack of response. If the issue is still reproducible with the latest Firefox version, feel free to reopen the bug with more information.
Thanks,
