845379 - SpecialPowers doesn't work in mozbrowser iframes

Status: NEW

(Core :: DOM: Core & HTML, defect, P5)

Description

[(no longer active)]

STR: Modify http://mxr.mozilla.org/mozilla-central/source/dom/browser-element/mochitest/file_browserElement_SetVisibleFrames_Outer.html?force=1 to access SpecialPowers.whatever, and then run http://mxr.mozilla.org/mozilla-central/source/dom/browser-element/mochitest/test_browserElement_oop_SetVisibleFrames.html?force=1.

This makes it impossible to fix bug 844169.

I believe it's specifically OOP ones.

I believe what we've done in other tests is proxy the calls to SpecialPowers up out of the browser frame.  This is not always feasible, depending on what you're trying to do.

You can make a call into the "main" frame by using alert("foo") and then listening to mozbrowserprompt (?) in the page which embeds the mozbrowser.

As described, it doesn't sound like OOP is the problem here - Outer is the non-remote frame.

No, I think OOP is the problem here.  Outer is loaded into a mozbrowser itself.

According to http://mxr.mozilla.org/mozilla-central/source/dom/browser-element/mochitest/browserElement_SetVisibleFrames.js#43, the frame that loads Outer is explicitly not remote.

Yeah sorry I don't know what I was talking about.

And looks like I can work around this in bug 844169.
