uMatrix browser add-on causes white pages when visiting Discourse instances

[reitzig (Raphael)]

For quite a while now, every time I visit any deployment if Discourse – this one, GitHub, Swift, Kotlin, Elm, … – I only get a white page. After a force reload (Ctrl+F5), the page will load and then work until I close that tab. Every new tab or soft reload (F5), same thing.

In the dev console, I see numerous errors:

I’m on Ubuntu 18.04, Firefox 76.0.1 (64-bit), uMatrix.

uMatrix config, since I can only post one image per post:

Does it work if you uninstall all browsers extensions ?

Can you open https://aws1.discourse-cdn.com/github/assets/ember_jquery-1ed3f3559e6f967733b4088aa729ff7039dff2c09c5a5f787a214b016f58aabc.br.js directly in another tab?

Can you curl that URL ?

[mmcm (Daan)]

Just came because I stumbled over the same thing, in a few different instances, over the last days.
I have the same setup (well, Firefox Nightly, but also with uMatrix) and was seeing the same errors.

For me, enabling XHR for both of the cloudfront subdomains (on this instance here) did the trick.

I’m not sure why that would be the case; uMatrix doesn’t indicate any XHR requests to those domains, but that seems more like a bug on their side, not discourse. I’m also unsure why a force-reload (Ctrl+F5) would help in this case, but it consistently does. Without allowing XHR, every page reload (not navigation, just the reloads with F5 or opening a new tab) will blank the page.

Anyway, hope this helps anyone who also stumbles over this.

[reitzig (Raphael)]

Curious indeed! Can confirm that it works here.

Sadly, though, a similar attempt on github.community doesn’t work:

[reitzig (Raphael)]

discuss.kotlinlang.org seems to work (though I’m not logged in currently; not sure if that makes any difference):

[supermathie (Michael Brown)]

@mmcm

Yes, exactly. If you install a browser extension that significantly affects the operation of that browser and disallows normal requests, you’re going to have a bad time.

[mmcm (Daan)]

@supermathie yes of course it does.
Installing uMatrix has always been an invitation to adventure. It’s curious that it breaks in this particular way here, but then it’s also really not discourse’s fault.

But uMatrix also consistently improves my experience of pages once I figure out how to run them without all the bloat & ads & annoyances, so I’m willing to take up a fight for it any day.
It’s just a bit sad that discourse pretty often ends up as collateral there; most discourse deployments I’ve seen have a pretty privacy-friendly setup: just two or three domains that have pretty clearly defined, user-value-providing tasks.

FWIW, serving all content from the same domain consistently works with uMatrix’s default 1st-party rules. I’m not a devops kinda person so I don’t know if that makes any sense, but from what I’ve seen it works quite nicely for small-to-medium size communities.

[riking (Kane York)]

Ah, this would be because of the serviceworker caching. All the resource requests get proxied by a script, so you need to allow the script to make requests (the XHR box).

And that’s the default for open-source Discourse installs, but we have large customers on our hosting so it’s easier to just give the CDN to everyone

[reitzig (Raphael)]

@supermathie

Yes, exactly. If you install a browser extension that significantly affects the operation of that browser and disallows normal requests, you’re going to have a bad time.

Web-app developers can keep in mind script blockers are around and accommodate them (to some extend), they can feign ignorance, or they can go out of their way to hide requests so it’s all but impossible to configure the script blocker in the right way. I’ve seen all three, and there’s definitely a choice there.

@mmcm

Installing uMatrix has always been an invitation to adventure.

Yeah, but I don’t expect a site to require dependencies that don’t show up.

FWIW, though: uMatrix has been put into archive mode over a year ago. I’ve switched to uBlock Origin now and am currently evaluating how Discourse behaves. So far, it seems to be okay.

uBO doesn’t distinguish scripts and XHR, so maybe that’s why it works: the scripts dependency is visible, so after allowing that, the XHR goes through.
It also has (more) whitelisting, so that may play a role as well.

@mmcm

Hmm.

@riking

No offense – I don’t understand the whys and hows of that at all – but that seems to fall into the “go out of their way to hide requests” category. Would it be possible to declare a statically discoverable dummy dependency so that thing shows up in? Or, you know, show anything actionable as opposed to a blank page?

[reitzig (Raphael)]

FWIW, picking up the example from the OP:

→ white page

→ white page

→ loads, apparently fully functional.
(And I’m trusting that kxcdn.com is nothing malicious here – might be a tracker for all I know. I’ve been on sites that wouldn’t load when Google Analytics was blocked! Point is, I have to trust Discourse here to see anything.)

I’m not complaining about having to click the buttons – I opted into that behaviour by blocking 3rd-party stuff by default, as you can see. My point is that a site/app would to well to serve more than white pixels in such a scenario.

PS: Nice to see the platform still treats me like a bot. Not.

On what page do you see that domain being referenced?

That’s the backend CDN behind e.g. sjc1.discourse-cdn.com but as far as we know, that bare name shouldn’t be anywhere.

@reitzig

I’ve switched to uBlock Origin now and am currently evaluating how Discourse behaves. So far, it seems to be okay.

I run daily with both uBlock Origin in my browser (default configs) and piHole in my LAN handling all DNS. I can guarantee that Discourse will work just fine with that, as multiple people in the team use the same tools.

@reitzig

Would it be possible to declare a statically discoverable dummy dependency so that thing shows up in? Or, you know, show anything actionable as opposed to a blank page?

There is content in the page under a no-script tag, that will be rendered if you go and tell your browser to not render Javascript. You will still be able to consume content in any Discourse install with JS disabled.

Disabling some JS is harder to gracefully fallback, as for us it would involve detecting that using JS

[reitzig (Raphael)]

@supermathie

On what page do you see that domain being referenced?

uBO displays it; see the screenshots above.

As far as I can tell, uBO resolves redirects and such to indicate where stuff is actually loaded from.

@supermathie

That’s the backend CDN behind e.g. sjc1.discourse-cdn.com but as far as we know, that bare name shouldn’t be anywhere.

So you’re hiding 3rd-party resources/services behind a domain chosen to look like it’s basically 1st party? Huh.

@Falco

Disabling some JS is harder to gracefully fallback, as for us it would involve detecting that using JS

I’m not a frontend person, but it seems possible to serve a static page that gets overwritten by loaded JS (if any), or use 1st party scripts for a minimal view, or use a 1st-party script to check wether the 3rd-party dependencies loaded, or … I don’t know, but plenty of pages manage to detect my nasty-nasty “ad blocker” and hide their content behind a veil of blur, so it seems the technical hurdles are surmountable. (Not that I want to suggest an ad-wall or anyting like that!)

Anyway, the immediate issue at hand is solved and I’m happy not having to force-reload every Discourse page. I think I also made my stance on 3rd-party dependencies in general and “reactive” websites reacting to missing ones clear. I’ll leave you mainainters to hash our whether there’s something to act on in here for you. Thanks for the help and time, and the good work in general! :wave

If you visit kxcdn.com in your browser, you’d see it is a CDN or Content Delivery Network for static assets, and a reasonably well known one. Other competitors are Amazon CloudFront, Cloudflare, etcetera. I’m not following what would be malicious about a CDN?
