User Agent: Mozilla/5.0 (X11; Ubuntu; Linux x86_64; rv:60.0) Gecko/20100101 Firefox/60.0
Build ID: 20180607190419
Firefox for Android

Steps to reproduce:

1. Create and run a page with this content:

```
<body></body>
<script>
	const source = document.createElement('canvas');
	source.width = 2048;
	source.height = 2048;
	document.body.appendChild(source);

	const sctx = source.getContext('2d');
	sctx.fillStyle = 'rgb(255, 0, 0)';
	sctx.fillRect(0, 0, 2048, 2048);

	const animate = () => {
		sctx.createPattern(source, 'repeat');
		requestAnimationFrame(animate);
	};
	requestAnimationFrame(animate);
</script>
```

2. It's possible that it only happens when hardware accelerated graphics are enabled


Actual results:

It eats `width * height * channels` memory on each execution, and does not release it.

Look at it with any memory measuring tool other than devtools heap snapshot, and look at quickly rising usage.

`about:memory` shows it as `heap-unclassified`

    #08: mozilla::dom::CanvasRenderingContext2D::ReturnTarget(bool) (/usr/local/src/gecko/dom/canvas/CanvasRenderingContext2D.cpp:2044)
  }
}
```


Expected results:

1. Free memory as needed
2. At least warn the user about page slowing down the browser/chomping up memory - nothing is reported currently

Additional profiling tools for such circumstances would be really nice (same goes for something more descriptive than `heap-unclassified` in `about:memory`)
Not a security bug.

Can you still reproduce this? If so, please paste your about:support contents to confirm I'm using a comparable configuration. I tried a few builds on Ubuntu without any memory reporting tool -- release, latest nightly, and 20180607220114 -- but could not reproduce. I note that doesn't seem like 20180607190419 is a valid Linux build? Thanks!

I reported it from my main browser (release channel), sorry about the version confusion. It still occurs in version built from source, and here is most of the info from about:support
