Steps to reproduce in Nightly:

1. Enter this URL: http://eca.hinet.net/download/HRCA_b64.crt
2. Click on "View" button to examine cert - nothing happens.

When folks use such a URL to import a cert, they must be able to examine the cert to make sure it is what they are expecting before they trust it.

The problem is that here:

https://searchfox.org/mozilla-central/rev/878bbf3cb8897a208454df27535f3522ab482cf2/security/manager/pki/resources/content/pippki.js#34

The ownerGlobal is that of the import dialog, not the browser window. You can get the actual latest browser window like this: https://searchfox.org/mozilla-central/rev/878bbf3cb8897a208454df27535f3522ab482cf2/browser/base/content/utilityOverlay.js#1005

So this should be easy to fix.

Apparently we have no tests for this, so it would be nice to add a test (maybe add it to the test that we have for opening about:certificate from different sources).

Danielle, Carolina, do you think one of you would be able to take this?

I can work on this! :)

Thanks!

Uhm, that's strange. I ran that test multiple times locally and I see sometimes it passes and sometimes it doesn't. I have no clue what should be going wrong here, Johann, do you have any insights on it? Thank you

Hi Carolina, great question! I think what you're seeing here is an early "about:blank" load that can happen before the actual about:certificate page is laoded (for various complicated reasons). So about:blank loads and the waitForNewWindow function picks up on it because we told it to return on the first load in the new window. Luckily waitForNewWindow takes a "url" parameter that can be a string or a function which will check if the url that's loaded is the correct one and only return then.

I've made a small change to your test that looks like this:

https://hg.mozilla.org/try/rev/e3d1959914058f838b01f4902a0b1f08995dcabf

And pushed to try to see if that's successful:

https://treeherder.mozilla.org/#/jobs?repo=try&revision=285d68034a23ef2295fa9687cbe60b56b2cb38ab

If that works you can just incorporate that change into your original patch and try to land again.

Thanks!

Thanks a lot Johann!
