1493699 - Immediate Crash upon visiting Website

Status: RESOLVED DUPLICATE of bug 1493211

(Core :: DOM: Service Workers, enhancement, P2)

Description

[Sean Stangl [:sstangl]]

Visiting the following URL in Nightly (x86_64, Linux) causes an immediate, 100%-reproducible crash: http://tonsky.me/blog/disenchantment/

Sample crash report: https://crash-stats.mozilla.com/report/index/3a5d1bdf-6784-4ce9-80c1-999360180924

The specific assert that's tripping is:

```
MOZ_RELEASE_ASSERT(spec.LowerCaseEqualsLiteral("about:blank") || StringBeginsWith(spec, static_cast<const nsLiteralCString&>(nsLiteralCString("" "blob:"))) || nsContentUtils::StorageAllowedForWindow(aInnerWindow) == nsContentUtils::StorageAccess::eAllow)
```

Any ideas, Andrew? It looks like you reviewed the patch that added this assert.

This is bug 1487227, triggered by the embedded twitter video using a no-fetch SW, but before duping over...

:sstangl are you using any of the tracking protection modes?  In particular, I'm interested if "Third party cookies" is enabled and set to "trackers" or potentially "all third-party cookeis" under about:preferences' privacy tab.  (This setting is also reflected/duplicated in the "Cookies and site data" below.)  The state of the other content blocking settings is also relevant.  Thanks!

[Sean Stangl [:sstangl]]

From about:preferences:

Content Blocking is On.

Slow-Loading Trackers is On.

All Detected Trackers is On, set to Only in Private Windows.

Third-Party Cookies is On, set to Trackers.

DNT is set to Only when Nightly is set to block Detected Trackers.

Cookies are set to "Block cookies and site data", with a block type of "Third-party trackers."

As bug 1493211 is resolved, can we close this one, too?

[Andrew Sutherland [:asuth] (he/him)]

Yes. And I did visit the reproducing site in question as a cursory sanity-check.
