Kyle can you reproduce this?  Any sense of where this work will be fitting into your next 6 weeks?

I haven't tried to reproduce this, but I strongly suspect this is a duplicate of Bug 789846.

Comment 3

[Alice0775 White]

Bug 789846 did not fix this problem...
I can still reproduce.

I don't think session restore is required; it looks like http://www.mozilla.org/en-US/firefox/central/ never finishes loading.  I'll dig in.

I think I've figured this out.

Attachment: Patch

Unfortunately we need to continue tracking whether or not the request is blocking onload in nsImageLoadingContent.  Otherwise we can run into a situation where when BlockOnload is called the <img> is in the document but when UnblockOnload is called it has been removed.  I considered using the owner document instead of the current document, and not tracking the load-blocking status, but that would make <imgs> that aren't in the document block onload, which seems undesirable.  We'd also still have to handle adoptNode ...

this should go into Beta 2, it's reproducible so let's get some verification in the next couple weeks.

[Anthony Hughes (:ashughes) [QA]]

Ioana, can you please have someone on your team at Softvision do some regression testing around this? We want to make sure it is fixed in Firefox 18.0a2 and 19.0a1. Thanks.

Verified on Firefox 17 beta 5, Aurora 18.0a2 and Nightly 19.0a1 that the session restore completes properly (if is closed unexpectedly or intentionally).

Verified on Windows 7, Ubuntu 12.04 and Mac OS X 10.7
