I don't like this wording, as "during navigation" isn't very precise. I think a user - even a web developer - would colloquially consider "while a new page is still loading" to be "during navigation".

Perhaps "Use of window.print is not allowed while unloading a page", or some variant thereof?

Same comment

> +        printErrorMessage("Use of window.confirm is not allowed during navigation.");

Same comment.

Same.

You guessed it.

Seems unrelated?

Removes the expected result but keeps the test?

r=me with comments.

> Source/WebCore/loader/FrameLoader.cpp:2822
> +void FrameLoader::handleUnloadEvents(UnloadEventPolicy unloadEventPolicy)

I think 'handle' is a bit vague, maybe 'dispatch' would be clearer?

> Source/WebCore/loader/FrameLoader.cpp:2825
> +    Page* page = m_frame.page();

nit: I like auto* for these things.

> Source/WebCore/loader/FrameLoader.cpp:2827
> +        page->forbidPrompts();

nit: I think it'd be nicer to have an object that calls forbidPrompts() in its constructor and allowPrompts() in its destructor. That object's constructor could take a Page* in parameter and take care of doing the null checking for us as well.
We could ForbiddenPromptsScope or similar.

> Source/WebCore/loader/FrameLoader.cpp:2829
> +    if (m_frame.document()) {

It looks like this whole method does nothing if m_frame.document() is null so I think we can return early here.

Ref<>

I agree. I'll make this change in a follow-up patch, since other functions in the class and related classes use "handle" for load and beforeunload, and I don't want to create inconsistency.

Removed this change because dispatchEvent requires PassRefPtr.
