It just so happens that the changeset just prior to that bug is for bug 1296498 where we first enabled the new RDM redesign in Nightly only. If I test an earlier Nightly build like 20160915 and manually enable new RDM by flipping "devtools.responsive.html.enabled" to true first, the problem is still present. My assumption is that this is a bug in new RDM that needs to account for user context somewhere.

ni? me to investigate complexity here.

Tanvi, as per our conversation on IRC, I went through the STR mentioned in comment#0 and I couldn't reproduce the problem while using Private Browsing. Platforms: * macOS 10.12 x64 - PASSED * Win 10 x64 VM - PASSED * Ubuntu 16.04 x64 VM - PASSED
From my own testing, I agree with comment 5 that everything appears to behave correctly with RDM and Private Browsing. As for container tabs, it's more complex, as I sort of suspected. The main issue is that RDM uses swapFrameLoaders to move content between browsers. Additionally, it also uses <iframe mozbrowser> to hold the content. swapFrameLoaders fails when various properties of the source and destination frames don't match, and one of those is origin attributes (as I am sure you're well aware, since I've seen other bugs patching this code path for user context support). So, to support container tabs properly, something like the following needs to be done: 1. Define what it means for <iframe mozbrowser> to have a user context and implement * Should it use the same attribute as <xul:browser> or something else? 2. Change RDM to set the proper attribute on the new frame before swapping content in It's unclear to me whether all that will get done inside the 52 cycle that new RDM intends to ride the trains. I'll convert this to a meta-bug to track the various pieces, and let's tentatively track this as blocking new RDM. As a backup plan if this is too much to do in 52, we can add a temporary error message to RDM for container tabs to stop opening and avoid breaking the tab.

Note that Containers will be enabled in Firefox 50+ with Test Pilot. So if this crash issue isn't fixed, release users may experience it.
Let's play it safe here. I'll add an error notification for now in bug 1311358, so at least the tab doesn't break. Then we can add real support here without the time pressure.
No longer blocks: enable-rdm

Summary: [meta] responsive mode crash (display blank page) when used within a container tab → [meta] RDM support for container tabs
Hello. I'd love to see it work too. My use case is this one: I have the website of my company which I develop. I would like to visit it in two ways: - classic user - dev user For the dev user, I'd like to have a neutral environment, so I use containers for that. However RDM doesn't work with containers. So I had to switch like: I use "home" container for watching the website as user, and no container for dev this website. It's not the best way because as I don't have containers when I dev on it, I've got all my browser history with me when I visit it. But for the moment it works. So I'll be really glad to be able to have all dev features when I use a container. :)
I'm a developer, and this would be very convenient.

I can confirm that the issue no longer occurs on the latest Nightly 62.0a1 (2018-06-11) - 20180611220254 - across Windows 10 x64, Ubuntu 16.04 and MacOS High Sierra 10.13 platforms. Responsive design mode works as expected in container tabs.
